I've been hitting my head all day over awk and
sed (grep?)!
My challenge is to search a directory of text files
for a string which I want to replace wherever it
occurs with a new string and save the file with
the changes in the same original file name.
Try a loop using grep with the -q option to locate the files with the
requisite text then sed with the -i option to make the change.
Something like:
cd /path/to/directory/
for FILE in
do
if grep -q "text to be replaced" "$FILE"
then
sed -i 's/text to be replaced/replacement text/g'
"$FILE"
fi
done
Notes:
1. "grep -q" does not need to be in [test brackets] because it is
a test in its own right
2. if you have filenames with spaces or funny characters it serves
yourself right.
