Inline "Sed" script

Sean OB_1 — Wed, 15 Dec 2004 13:12:23 GMT

Howdy.

Years ago I had a script that essentially did inline sed on files.

With it you'd call the script and give the sed command, it would then run against the file(s) you specify and do the sed and save the file.

Does anyone have something like this that they'd be willing to post?

TIA.

"perl" can do that and more-

perl -p -i -e 's/this/that/g' allmyfiles/*

Will replace the text in all the files under directory allmyfiles.

Change option -i to -i.bu and it will save a backup of each file with an extenstion of .bu.

Try this

#!/usr/bin/sh
TMF=/tmp/$$
PRGN=$(basename $0)
if [ $# -ne 3 ]; then
echo "$PRGN:USAGE $PRGN FILENAME CURR CHANGE"
exit
fi
if [ -s $1 ];then
cat $1| sed "s?$2?$3?g" > $TMF
if ! diff $1 $TMF 1>/dev/null ;then
cp $TMF $1
fi
else
echo "$PRGN:File $1 NOT FOUND"
fi
rm $TMF
