Question:
I'd like to replace 'blue' with 'red' in file 'month.log' in 3000+ users
directories. All users are under /home directory. How do I do this. Thanks
for your help.
Solution:
for DIR in /home/*
do
sed s/blue/red/g $DIR/month.log > $DIR/newmonth.log
mv $DIR/newmonth.log $DIR/month.log
done
--------------------------------------------
cd /home
for FILE in */month.log; do
ex $FILE >/dev/null <<EOF
%s/blue/red/g
wq!
EOF
done
---------------------------------------------
perl -p -i -e 's/original text string/replacementstring/g' foo
---------------------------------------------
#!/usr/bin/sh
sed -e "s/blue/red/g" $1 > /tmp/sed.temp$$
if [ $? ]; then # only when the sed went ok!
mv /tmp/sed.temp$$ $1
fi
----------------------------------------------
