removing strings from filename

aliyesami · #1 (**permalink**) 06-08-04, 09:10

if I have filenames like this k_tape_dis_06082004.txt , how can I remove the date string appearing in there using KsH ? so the file should look like
k_tape_dis.txt

Code:

#!/bin/ksh

file='k_tape_dis_06082004.txt'

echo "file->[${file}] changed->[$(echo "${file}" | sed -e 's/^\(.*\)_\([0-9][0-9]*\)\(.*\)/\1\3/g')]"

..... with the ksh's builtins:

Code:

#!/bin/ksh

file='k_tape_dis_06082004.txt'

echo "file->[${file}] changed->[${file%%_${file##*_}}.${file##*.}]"
