Hello,

for everyone who wanted to know how to get the return code or status from an executed command in unix:

# for example use the ls command on a directory
ls -l /home

# get return code
echo $?

This returns an integer code as 0 or 1 or 127. Normally 0 means OK, 1 means ERROR and 127 means COMMAND NOT FOUND. Every command has its own return code but the 3 mentionned before are general.
