i am using laravel on docker . i run my project when i exec into container and use
php artisan tinker
no matter what command i run i receive this error :

any idea what can be wrong here ?

Busybox contains cutdown versions of many Unix/Linux utilities, including less. Either remove it and install the less package, as well as the other utilities it mimics, or hack artisan and remove the -X switch against /usr/bin/less. All the -X switch does is sort alphabetically by entry extension

Ugh just spent a ton of time messing with this one myself.
The root cause of this issue is the upgrading of the psypsh shell package that tinker users.
You can see in the release notes here https://github.com/bobthecow/psysh/releases/tag/v0.11.3
There are a few ways around this, as mentioned above, you can just install the less package using apk or apt-get.
You can also set the cli.pager property in your php.ini file to explicitly call less without the -X switch.

Why piping output of docker-compose exec to grep, breaks it?

I'm running this command to run Drush which is basically a PHP CLI for Drupal, in the running container:
docker-compose -f ../docker-compose.test.yml exec php scripts/bin/vendor/drush.phar -r public_html status-report
The output if this command is fine, it's the list of status information about a specific Drupal instance in the container. I won't be pasting it here as it's long, and irrelevant.
Now let's filter this information by piping it into grep:
docker-compose -f ../docker-compose.test.yml exec php scripts/bin/vendor/drush.phar -r public_html status-report | grep -e Warning -e Error
The result is:
Cro Error L
Gra Warning P
HTT Error F
HTT Warning T
Dru Warning N
XML Error L
Which is wrong, it looks like it has been cut to pieces, and most of it is missing.
Now, if we will disable allocating of pseudo-tty by adding -T flag:
docker-compose -f ../docker-compose.test.yml exec -T php scripts/bin/vendor/drush.phar -r public_html status-report | grep -e Warning -e Error
The output is correct:
Cron maintenance Error Last run 3 weeks 1 day ago
Gravatar Warning Potential issues
HTTP request status Error Fails
HTTPRL - Non Warning This server does not handle hanging
Drupal core update Warning No update data available
XML sitemap Error Last attempted generation on Tue, 04/18/2017
Why is that?
Bonus question, which probably will be answered by the answer to the previous one: Are there any important side effects of using -T?
Docker version 18.06.1-ce, build e68fc7a215
docker-compose version 1.22.0
UPDATE #1:
To simplify things I saved the correct output of the whole scripts/bin/vendor/drush.phar -r public_html status-report into a file test.txt and tried:
docker-compose -f ../docker-compose.test.yml exec php cat test.txt | grep -e Warning -e Error
Interestingly the output is correct now with and witout -T, so it has to have something to do with Drush/php, although I'm still interested what can be a cause of this.

UPDATE #2:
To isolate problem further I put all content in a PHP file, that is simply printing it, and after:
docker-compose -f ../docker-compose.test.yml exec php php php.php | grep -e Warning -e Error
I'm getting a correct output!
So it has to have something to do with how Drush is printing its messages, but I fail to see what it can be. That could be pretty interesting if we could figure this out.
UPDATE #3:
Ok guys, that's actual magic. The problem happens also with running drush without any commands, to list all available ones. The list of commands is broken when output is being piped, so this can be tested without actual Drupal instance.
Now I want to present you magic.
In drush, output for list of available commands in being generated in commands/core/help.drush.phpin function drush_core_help(). There is this call: drush_help_listing_print($command_categories); I looked into it. Inside is a call drush_print_table($rows, FALSE, array('name' => 20)); that is responsible for generating part of the output that's getting broken.
So inside of it, I decided to intercept the output, just before the last call to drush_print(), by adding simple file_put_contents('/var/www/html/data.txt', $output);
And now it's time for the absolutely magical part for me.
When I execute:
docker-compose -f ../docker-compose.test.yml exec php scripts/bin/vendor/drush/drush -r public_html
The last group of commands can be checked in this file, and in my case it's:
adminrole-update Update the administrator role permissions.
elysia-cron Run all cron tasks in all active modules for specified site using elysia cron system. This replaces the standard "core-cron" drush handler.
generate-redirects Create redirects.
libraries-download Download library files of registered libraries.
(ldl, lib-download)
libraries-list (lls, Show a list of registered libraries.
lib-list)
BUT, if I execute the same command, but the output will be piped or redirected, so for example:
docker-compose -f ../docker-compose.test.yml exec php scripts/bin/vendor/drush/drush -r public_html | cat
SOMETHING DIFFERENT WILL BE SAVED INTO A FILE:
adminrole-update U
p
d
a
t
e
t
h
e
a
d
m
i
n
i
s
t
r
a
t
o
r
r
(and the rest of the broken output)
So the fact of piping/redirecting of the output, influences execution of the command, before the pipe/redirection actually happens.
How is that even possible? O_o
It's not uncommon for a command-line program to change its output presentation based on whether its output is a terminal, or not. For example, ls by itself, with no options, displays files in a columnar format. When piped, the output changes to a list of one-file-per-line. You can see this in the source code for GNU ls:
case LS_LS:
/* This is for the 'ls' program. */
if (isatty (STDOUT_FILENO))
{
format = many_per_line;
set_quoting_style (NULL, shell_escape_quoting_style);
/* See description of qmark_funny_chars, above. */
qmark_funny_chars = true;
}
else
{
format = one_per_line;
qmark_funny_chars = false;
}
break;
You can emulate the behavior of ls | ... with the explicit argument ls -1, and this too is not uncommon: programs that implicitly change their output presentation often provide a way to explicitly engage that alternate presentation.
Support for this isn't just a convention: it's actually a requirement for ls in POSIX:
The default format shall be to list one entry per line to standard output; the exceptions are to terminals or when one of the -C, -m, or -x options is specified. If the output is to a terminal, the format is implementation-defined.
This all may seem magical: how does ls know it's got a pipe following it since it comes before the pipe? The answer is quite simple, really: the shell parses the whole command line, sets up the pipes, and then forks the respective programs with the input/output wired to pipes appropriately.
So, what part of the command is doing the alternate presentation? I suspect it's an interaction between the environment of your exec and the column width calculation in drush. On my local environment, drush help | ... doesn't produce any unusual results. You might try piping to (or through) cat -vet to discover any unusual characters in the output.
That said, regarding docker-compose specifically: based on this thread, you're not the only one who has encountered this or a similar issue. I've not trawled the docker source code, but - generally - not allocating a pseudo-tty will make the other end act like a non-interactive shell, which means things like your .bash_profile won't run and you won't be able to read stdin in the run command. This can give the appearance of things not working.
The thread linked above mentions a work around of this form:
docker exec -i $(docker-compose ...) < input-file
which seems reasonable given the meaning of -i, but it also seems rather convoluted for basic scripting.
The fact that -T makes it work for you suggests to me that you have something in your .bash_profile (or similar login-shell-specific start up file) that's changing certain values (maybe COLUMNS) or altering the values in such a way as to have the observed deleterious effect. You might try removing everything from those files, then adding them back to see if any particular one causes the issue.
I didn't read that very detailed question, but from glancing over it, I'd say the -T option to the exec subcommand is essential if you want to process stdout and stderr in the environment where you execute docker-compose.

Why is PATH on mac not working? [duplicate]

Can anyone explain how python 2.6 could be getting run by default on my machine? It looks like python points to 2.7, so it seems like which isn't giving me correct information.
~> python --version
Python 2.6.5
~> which python
/opt/local/bin/python
~> /opt/local/bin/python --version
Python 2.7.2
~> ls -l /opt/local/bin/python
lrwxr-xr-x 1 root admin 24 12 Oct 16:02 /opt/local/bin/python -> /opt/local/bin/python2.7
When I generate an error, I see what's really getting run. Why could this be?
~> python -error-making-argument
Unknown option: -e
usage: /Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.
And how can I correct it?
From suggestions in comments:
~> alias
alias cp='cp -i'
alias gcc='gcc -Wall'
~> type python
python is /opt/local/bin/python
Bash uses an internal hash table to optimize $PATH lookups. When you install a new program with the same name as an existing program (python in this case) earlier in your $PATH, Bash doesn't know about it and continues to use the old one. The which executable does a full $PATH search and prints out the intended result.
To fix this, run the command hash -d python. This will delete python from Bash's hash table and force it to do a full $PATH search the next time you invoke it. Alternatively, you can also run hash -r to clear out the hash table entirely.
The type builtin will tell you how a given command will be interpreted. If it says that a command is hashed, that means that Bash is going to skip the $PATH search for the executable.
I just checked my .bash_profile, and it contained the following:
# Setting PATH for MacPython 2.6
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.6/bin:/usr/local/git/bin:${PATH}"
export PATH
Commenting this out has fixed my problem.
If someone can tell me why which and type still gave incorrect answers, I'd be very grateful, and will give them a check-mark!
Thanks for all your guidance!

Call LLVM-GCC in PHP

I tried to generate LLVM intermediate code by calling
llvm-gcc -emit-llvm -I/mypath/ -c main.c -o main.o
It works perfectly without any warnings or errors if I manually type this command in the terminal.
However I have built a website that can automate this process by calling exec function in PHP like below.
exec("llvm-gcc -emit-llvm -I/mypath/ -c main.c -o main.o",$msg,$ret);
It will still generate .o file with a warning. The warning says that
Potential incompatible plugin version. GCC: 4.5.3. Expected: 4.5.4
Defines 'dragonegg_disable_version_check' as env variable to remove this warning.
Please note that unexpected errors might occur.
The php command will still return 0, which is successful. However when I run the generated .o file, it will throw invalid bitcode signature error.
The server is running ubuntu and Apache. My llvm-gcc version is 2.9 which uses 4.2.1 gcc.
Any help will do. Thank you!
The best thing would be to update the GCC to 4.5.4. But if you just want to hide the warning, simply define dragonegg_disable_version_check.
$command = 'dragonegg_disable_version_check=1'
. ' llvm-gcc -emit-llvm -I/mypath/'
. ' -c main.c -o main.o';
exec($command,$msg,$ret);
For the invalid bit code signature error -- see this questions.

php cli on linux not working

PHP CLI has suddently stopped working on the server. When running any php file even php -v to get php version I get following error.
Thanks
# php -v
Unknown option: v

-s,--string string
"string" will be the input instead of STDIN or files
The following are mainly of interest to Encode hackers:
-D,--debug show debug information
-C N | -c | -p check the validity of the input
-S,--scheme scheme use the scheme for conversion
Type which php on your shell to find which php executable your shell picks from your search PATH.
Use ls -l $(which php) to see if it's a symlink to some other executable.
What you see when running php -v is actually output of the piconv command.
Most possibly, there is a symlink named php pointing to piconv somewhere in your search PATH.
Type echo $PATH to see the order of directories in which your shell searches for an executable php.
EDIT:
Changed whereis to which in the command above.

Calling git from PHP: Broken pipe error

I have the following PHP script:
#!/usr/bin/php
<?php
echo shell_exec(
"/usr/bin/git clone --bare ".
"/home/dave/create_project/template_project ".
"/home/dave/create_project/my_test_project.git"
);
About 7 in 10 times that I run it, git gives the following error:
find: write error: Broken pipe
This error never occurs if I run the equivalent command directly from the shell.
I have already tried:
using other PHP execution functions: exec, system, popen;
passing the whole command as an argument to bash, i.e., exec('bash -c '.$cmd);
Does anyone have any idea what might be going on?
It may depend on your exact platform, but findutils has been known to throw that kind of error message before.
On Fedora, that rpm package version 4.2.33-2.fc9 fixed the issue.
Does PHP throw any errors? Maybe max_execution_time is too low? Mu guess PHP app exites prematurely.
