Replace spaces with tabs & format file source recursively within a directory

find . -type f -name \*.php | while IFS="" read i; do expand -t4 "$i" > "$i-"; mv "$i-" "$i"; done
Recursively find php files and replace tab characters with spaces. Options: "\*.php" -- replace this with the files you wish to find "expand" -- replace tabs with spaces (use "unexpand" to replace spaces with tabs) "-t4" -- tabs represent 4 spaces Note: The IFS="" in the middle is to prevent 'read' from eating leading/trailing whitespace in filenames.

What Others Think

flatcap, it expands/unexpands *all* file contents. Isn't it? While my command uses smart vim formatting to *indent* using tabs, not touching those in strings, for instance

Really? Unfortunately, I can't get your command to work. From the vim help on retab: Careful: This command modifies any characters inside of strings in a C program. Use "\t" to avoid this (that's a good habit anyway). By adding --initial to expand (or --first-only to unexpand), it will only work on leading whitespace. As a heavy user of vim, I'd have done this by macro or bufdo. Spawning vim for every file will really slow things down.

flatcap, what about constructions like $a = array( 'key1' => '12', 'longlongkey' => 'someghing', 'second-long-k' => 12.34, ); ?

It didn't format like what I mean. Look at this:

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
