Re: Multible search and replace?
When Joey Hess wrote, I replied:

Was just wondering if there is a package out that does multiple file
search and replaces? I have to go through my main html directory and make
a lot of repetive changes. Was wondering if there was a package or a perl
script laying arround to do this. Would same me the time of writing one
up.
Well, this is so easy to do in perl that I just write little programs to
do it on the fly most of the time. Here's a little program that may do
what you want:
#!/usr/bin/perl -i.bak
$find=shift; $replace=shift;
while () { s/$find/$replace/g; print }
Name it replace and call it like so:
replace from to file [file ...]
It can operate on multiple files, 'from' is the string you want to find,
and it is replaced globally with 'to' in all the files. Backups are saved
with a .bak extention.

Well, not with the example I gave you can't, but if you use something like
this, you can use all those wonderful perl regexp tricks:
#!/usr/bin/perl -i.bak
$find=shift; $replace=shift;
while () { eval s/$find/$replace/g; print }

You'd have to execute it once for each change to me made, but at least it would do all the files each time. Wow! For a modeless editer, emacs sure has a lot of modes! In any reasonable vi clone (e.g. nvi, vim, elvis, etc.) you have basically two modes: insert and command. If your in insert, hit the escape key to get into command mode. Then just type a colon : and enter %s/text to replace/text to replace with/g. This is pretty standard syntax for this sort of thing in unix. The % is a short cut for specifying all lines in the file which could be done with 1,$ longhand. The s is swap or switch or something like that. The first slash marks the begginning of the search text. The second slash separates that from the replacement text and the last ends the text spec. The g indicates a global operation for each line specified (in this case all lines). The global specification is needed if you want all incidents of the search text on each line replaced. So, in vi just type: :%s/whatever/whatever else/g Very simple. The text can contain pretty much anything, but some stuff may need to be esaped with a back slash \ or input as is with a ^Vcharacter. Outside of that, I'm sure there must be some handy HTML editors that can do this as well. Thanks Richard G.

From: Chad Zimmerman [EMAIL PROTECTED] Was just wondering if there is a package out that does multiple file search and replaces? I have to go through my main html directory and make a lot of repetive changes. Was wondering if there was a package or a perl script laying arround to do this. Would same me the time of writing one up. Hopefully you'll get a more general answer too, but if you are an Emacs user, you probably want to know about this method: Outside of emacs, run etags, giving it the names of all the files in the subtree. For exapmle: cd wherever etags `find -type f` The in emacs, use the tags-query-replace command. (For this use of etags, the point is just to list all the files. It doesn't matter whether etags and emacs recognize any tags within the files.) Daniel P.S. This probably should go to a general Unix list, since it's not a specific Debian question. P.P.S.
