How do I run ruby commands in my bash script without getting "ruby: command not found"

Question

my script=

#!/bin/bash

echo ************************BEGIN LOG******************************>>/root/backup_scripts/new_scripts/vmbackup.log 2>&1
date +"%m/%d/%Y %H:%M:%S $HOSTNAME">>/root/backup_scripts/new_scripts/vmbackup.log 2>&1
ruby /root/backup_scripts/new_scripts/aapxen01.rb>>/root/backup_scripts/new_scripts/vmbackup.log 2>&1
ruby /root/backup_scripts/new_scripts/apvdbs03.rb>>/root/backup_scripts/new_scripts/vmbackup.log 2>&1
ruby /root/backup_scripts/new_scripts/aapxen02.rb>>/root/backup_scripts/new_scripts/vmbackup.log 2>&1

echo end log entry>>/root/backup_scripts/new_scripts/vmbackup.log 2>&1

my log=

************************BEGIN LOG******************************
09/28/2010 11:10:01 aapsan01.boingoboingo.local
/root/backup_scripts/new_scripts/run.sh: line 5: ruby: command not found
/root/backup_scripts/new_scripts/run.sh: line 6: ruby: command not found
/root/backup_scripts/new_scripts/run.sh: line 7: ruby: command not found
end log entry

my crontab this runs from:

PATH=/sbin:/bin:/usr/sbin:/usr/bin
[email protected]
HOME=/
LD_LIBRARY_PATH=/usr/local/lib/
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7)  OR
#sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  *  command to be executed
05 01 * * * /root/backup_scripts/run_backups.sh
22 11 * * * /root/backup_scripts/new_scripts/run.sh

This might seem like a dumb question, but do you have ruby installed? — Daenyth

It occurs to me that I should mention that I have this running from crontab. — Captain Claptrap

Put the directory that ruby lives in into your PATH. PATH=/usr/bin/:$PATH"; export PATH

You might also want to store this line in your .bashrc to avoid typing it each time you open up a terminal.

If the script is run from cron or some other background method, it won't inherit your PATH, so you need to make sure the PATH is set in the script.

Do I just add a line to the script like this? PATH=/usr/bin/ruby and put that under #!/bin/bash ?

Paul Tomblin Over a year ago

@micha, you need to write it the way I did above: PATH=/usr/bin:$PATH;export PATH

And of course, it will depend where ruby is installed on your system - I have mine in /usr/bin.

Have you tried adding the full path for ruby?

You need to specify the absolute pathname of the interpreter e.g. /usr/bin/ruby, or check why it does not appear in the $PATH of the environment of the user owning the crontab.
