As a 'one liner':

for file in *.[ch] ; do mv $file $file.bak ; expand -t 4 $file.bak 
 >$file ; done

And to save retyping it each time, add it into your .bashrc as an alias:

alias ctabs='for file in *.[ch] ; do mv $file $file.bak ; expand -t 4 
$file.bak >$file ; done'

???

grep & egrep will search for tabs:

egrep -e '\t' yourtabbedfile

works as expected.


Good luck,
