script to insert filenames into files

magnim · 03-22-2007, 01:06 AM

I have a few directories containing some text files (a couple thousand files total)
Trying to figure out how to go through the contents of a single directory and insert the name of each file into each of the files, along with some additional text before and after the filename.

Any help would be fantastic.

Hi there, and welcome.

Code:

ls > filename

will get your contents of a single directory into a text file, but I don't know about the other part. I think you will have to be more specific so that the other members will know exactly what you are trying to do.

Edit: Hang on, I just read it again, you want to put the filename into the file it belongs to, sorry. The above command won't do that, In fact, just ignore this post.
(I am tired an have a massive headache)

Sorry for any confusion.

Untested...

Caveat: this doesn't handle files with spaces in the names
Run once per directory ... or modify to match your needs
better.

Code:

for i in `ls *txt`; do echo $i "And other text" > tmp; cat tmp $i > $i.tmp; mv $i.tmp $i; done

Cheers,
Tink
