I had the following script that I sourced from .bashrc to let me know
when I was running out of disk space.
#!/bin/bash
df | grep dev | cut -c53-54,56- | while read p1 p2
do
if [ $p1 -gt 95 ]
then
echo "Danger! $p2 is $p1 full!"
fi
done
This worked fine under Mandrake 9.0 and RedHat 8.0. I've just spent 3
tortuous hours determining that sourcing this no longer works. Now I
have to simply run it. That is, before where I had
source ~/checksize.sh
now I must have simply
~/checksize.sh
The original method produces this:
bash: [: -gt: unary operator expected
bash: [: -gt: unary operator expected
bash: [: ha: integer expression expected
bash: [: oo: integer expression expected
bash: [: -gt: unary operator expected
The reason that I sourced it originally is that because I was starting a
shell script from within .bashrc, I got into an infinite loop. This no
longer appears to happen. Why does sourcing no longer work?
