[gentoo-user] [OT]batch processing html files
I have a folder full of .html files and I need to go through and replace in each and every one of them a couple of bits of info. I know I can do this using the following from the command line: sed 's/VV, ppp-ppp/81, 51-67/' file.html newfile.html | mv newfile.html file.html Problem is I need to do this on nearly 200 files. I assume it could be done with a script, but I have zero experience in writing scripts. I've looked through a few how-to's but haven't found anything I understand sofar. I want to learn how to script, but my Prof want's this done yesterday as the associated paper has just been published. Cheers Matt -- %%% Dr. Matthew R.

Cheers Matt bash to the rescue! try for: for n in *html ; do sed 's/VV, ppp-ppp/81, 51-67/' $n newfile.html ; mv newfile.html $n ; done That assumes that every html file in the current dir that contains VV must have it changed.

I assume it could be done with a script, but I have zero experience in writing scripts. If all the files are in the same directory, you can do cd /your/directory for f in *.html; do sed -i 's/VV, ppp-ppp/81, 51-67/' $f done The -i flag tells sed to edit the file in place, ie, the changes are made to the file itself (of course, sed does create a temporary file behind the scenes, but that is handled by sed). To stay on the safe side, I suggest specifying a suffix to -i, so that sed creates backup copies of the files, eg sed -i BAK etc. will create a backup file called $f.BAK when modifying $f. When you're sure the changes are correct, you can of course delete all the BAK files. Otherwise, use them to restore the original files and start over. Hope this helps. -- gentoo-user@lists.gentoo.org mailing list

Right, as an addendum to my other solution, in the case where files
are spread across a directory tree, run the following in the base
directory of tree:
find ./ -name *.html -exec sed -i.bkup 's/VV, ppp-ppp/81, 51-67/' {} +
(yes, that's a '+' character at the end). You can, of course, tweak
the parameter to find to get finer control of exactly which files you
want modified; this is left as an exercise to the reader.
