Need help writing a shell script

sanman_2 — Fri, 24 Nov 2000 18:11:48 GMT

please help me with this!!

I need to write a shell script that removes the characters given as the second argument from the end of the name of the file given as the first argument. So memo1.sv should rename memo1.sv to memo1.

Thanks for all your kind help!!!!

Hi,

A simple script with no error checking follows:-

#!/usr/bin/sh

FILE=${1}
SUFFIX=${2}
NEWFILE=${FILE%${SUFFIX}}

mv ${FILE} ${NEWFILE}
exit

Call it with:-

<scriptname>

Regards,
John

Try this:

#!/bin/sh
#
# renames without the last extension.

OLDNAME=$1
NEWNAME=` echo $OLDNAME | awk '{ n=split($1,filen,".")
for (i = 1; i < n ; i++ ) printf filen[i]"." }'`
mv $OLDNAME $NEWNAME

If you want to do it for any filename recursively:

#!/usr/bin/ksh
if [ $# = 0 ]; then
echo "Arg: fileSuffix"
exit
fi
MV=/tmp/mvSuff
echo 'mv $1 $(dirname $1)/$(basename $1 .'"$1"')' > $MV
chmod +x $MV
find . -name "*.$1" -exec $MV {} \;
rm $MV
