Script to delete text from the end of a filename
Hi all,

I am trying to write a script that will delete a certain amount of text from the end of a filename.

For example.

HTML Code:
Input:

name of file (more text).pdf

Output:

name of file.pdf
So is it possible to write a script the deletes, in this example twelve (12) digits from the end of the filename whether it be numbers, text, spaces or symbols?


Thanks! Smilie

ghostdog74,

I've learnt that the simpler way to do this would be to delete a certain amount of text from the end of the filename. This would be the easiest way to do it. I appreciate all the examples that people have given me - they work I just think this would be simpler.

Regards.

To start with the basics..to learn

Code:
a="name of file (more text).pdf"
b=$(echo $a | cut -d. -f1)
c=$(echo $a | cut -d. -f2)
d=${#b)n
wfile=$(echo $a | cut -c -12)
mv $a "$nwfile.$c"

echo after each command and see what does it o/p.


cheers,
Devaraj Takhellambam

ghostdog74,

This is what I have so far, running this from /bin/sh

Code:
for file in *.pdf
do 
mv $f `cut -c 12- <<END
$f
END
`
done

if your files always has the structure of "file name (more text).pdf', see here under "substring removal" for examples on string substitution. also get familiar with shell scripting by reading the whole document
