'sed -e' for each file. Output result for each file.

esed

#!/bin/bash
# esed 's/foo/bar/g' files....
script=$1
shift 1

CHANGED=1 # diff returns 1 for differences. (0 for no difference, 2 for errors.)
for file in $*
do
    sed -e ${script} ${file} > ${file}~
    diff ${file} ${file}~ > /dev/null
    if [ $? -eq ${CHANGED} ]; then
        cp -p ${file}~ ${file}
    fi
    rm -f ${file}~
done

Feature request: don't touch file which isn't modified.

How about this?

#!/bin/sh
# esed 's/foo/bar/g' files....
script=$1
shift 1

set CHANGED=1 # diff returns 1 for differences. (0 for no difference, 2 for errors.)
for file in $*
do
    sed -e ${script} ${file} > ${file}~
    diff ${file} ${file}~ > /dev/null
    if [ $? -eq ${CHANGED} ]; then
        cp -p ${file}~ ${file}
    fi
    rm -f ${file}~
done

Thank you, and it works!
