Column alignment

[jennydaman]

In the original script, columns would be misaligned because df is called several times on different mount points, so its spacing would be different when filesystem names differ in length.

I refactored the code to call df only once. $line is extracted using grep.

• titeled="1" was a filthy hack
• column spacing issue fixed
• This gives flexibility because you can specify either filesystem or mount point, but specifying / as a mount point won't work anymore.
