[SOLVED] Bash Scripting Error: EOF encountered in a comment?

dilzniksan · 06-02-2010, 09:42 AM

Here is my code and output:

Code:

#!/bin/bash
s=($(quota))
o=$(echo "scale=4;${s[17]}/${s[18]}*100."|bc -l)
printf "You have used %4g%% of your allocated space." $o

Code:

EOF encountered in a comment.
(standard_in) 1: syntax error
You have used    0% of your allocated space.

The script is working correctly with the exception of the error message.

The error is there, because the values s[17] and s[18] are empty. Then bc reads your command as "scale=4;/*100.", which produces the error. Check if 17 and 18 are correct.

You could try using ${s:17:1} and ${s:18:1} instead of ${s[17]} and ${s[18]}. To my knowledge, bash doesn't support accessing string chars by array indices.

Thanks Irmin, your answer makes sense as I wasnt receiving that error when I ran that script where quota's had been emplaced.

The next question is: how do I implement this script so that it runs whenever a terminal session has been started?

Do I add a gnome-terminal.sh file to /etc/profile.d?

~/.bashrc
