Grep/File Searching question

<< < (2/3) > >>

LorKorub:
I am using Korn Shell. And I did a reverse-video on it right from the board.

I'll try it in bash...

LorKorub:
Bitchin'....

Thanks, dude....

How exactly did all of that work?

EDIT:

Calum....I've been on the man pages and Google all night trying to find a simple way to do this.  I came up with the hypothesis that maybe you could use grep to find the line, pipe it to vi and use the Replace fucntion.....

...didn't work...LOL

Calum:
hey i hope i didn't sound condescending there, i haven't read the man pages, but these things you have both mentioned i think will have given me enough reading to sort out my own concern, so thanks to both of you!  :D

flap:
for i in `find ./ -name '*.php'`;
...for each line returned by the command find ./ -name '*.php'...

do sed 's/height=200px//g' $i > tmp;

...do the following: use sed to find every occurrence of the string "height=200px" in the filename denoted by 'i' and replace it with a blank string. the > operator then redirects the output of this command (which would otherwise just be printed to stdout i.e. the screen) to the file 'tmp'

mv tmp $i; done

...overwrite the original unmodified file with the tmp file

In windows, incidentally, the procedure is:

1. Open file in notepad
2. Use the 'Replace' facility to remove all unwanted strings
3. Save file
Repeat 40 times

Calum:
and to specify a value to replace the original value? (for instance, to replace the line with "height=400px")
