I saw this issue on Python 2.7.3 running on FreeBSD 9.1-64 and ubuntu 12.04-64. All under BASH. It seems that the shell for the external script does not have the access to RANDOM environment variable. If I run the script directly, the results are OK. # python -V Python 2.7.3 # ls *.sh arquery.sh randomnumber.sh # ./commands_bug.py -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION0.log # ./randomnumber.sh -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION0.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION279970795912919.log # ./randomnumber.sh -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION0.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION279970795912919.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION309000060807371.log # ./randomnumber.sh -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION0.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION20000681632594.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION279970795912919.log -rw-r--r-- 1 root netvcr 9 Feb 20 17:31 SESSION309000060807371.log # # randomnumber.sh #set -x # randomnumber=$((RANDOM*10000000000+RANDOM*100000+RANDOM)) sid=SESSION${randomnumber} echo "whatever" > ${sid}.log ls -l SESSION*.log #!/usr/local/bin/python # # bug_in_python.py # import os import commands def main(): cmdString = './randomnumber.sh' outputString = commands.getstatusoutput(cmdString) print outputString[1] # # program starts # if __name__ == '__main__': main() os._exit(0) |

I'm not sure that commands.getstatusoutput() will use the same shell than your shell. Try to display $SHELL environment variable to know your shell. |

Since commands is deprecated, closing the issue. |
