replacing a string in multiple subdirs to a new string??
I have following set of dirs:

/dir1/dir2/subdir1
file1
file2
/dir1/dir3/subdir1
file4
file5
/dir1/dir4/subdir1
file6
file7

All of these files have a common string in them say "STRING1", How can I replace "STRING1" to "STRING2" for all files.

Thanks in advance.

If you mean all the files in those subdirectories:

find /dir1 -type f -exec sed -i 's/STRING1/STRING2/g' '{}' ';'

If you mean specifically those and only those, just list them after sed like so:

sed -i s/STRING1/STRING2/g /dir1/dir2/subdir1/file[12] /dir1/dir3/subdir1/file[45] /dir1/dir4/subdir1/file[67]

Thanks for your reply.

It says "illegal option -i", we are on AIX V5.3

Your sed version doesn't support the inline option. Try this:

Code:
find /dir1 -type f | xargs -i bash -c "sed 's/STRING1/STRING2/g' {} > {}.bak; mv {}.bak {}"

Be careful with this as there is no way back. Do some tests first. You can also change the mv command by cp to keep a backup of original file.
