Search
and Replace
(ok,
it's not an original name...) replaces characters in
recursive
directories and files
line by line, with a strong
suite of options for prompted replaces. It's a medium size
utility written in Perl. It's very useful for replacing things
like domain names, etc.
On one client's
system it processed 13,029 files, with 7,487 replaces, in
11 seconds.
It also writes its operation output
to a log file, so you can check what it did.
I also use it to replace items in large data
sets that have been saved in text format. It's quite fast.
It processed 13,402,165 replaces, (13.4 million) (a 67 meg
text file with 163,441 lines) in 1 minute, 10 seconds on a
Pentium 166 with 64 megs of RAM.
As an alternate method, I recommend using VEDIT, the fastest
huge file text editor in the world, at 'vedit.com'.
I think VEDIT is
the FASTEST Text Editor in the WORLD!!! 2 MILLION replaces
in a 100 meg file in 1.51 minutes!!! I do a lot of
heavy duty database manipulation, on gigantic files. When
you have to WAIT and WAIT and WAIT (yawn) for other editors
to decide to even begin to do the million or so replaces that
you need to do, then you begin to say to yourself, "Oh, if
I only had VEDIT!!!!" :-) (It's true.) Smart programmers have
more than one editor in their toolbox, so they can do each,
very different job, with the best tool for the job.
BUY this editor today if you need speed. You won't regret
it.
(I fixed a 50 meg file
with 170,000 replaces multiple times using VEDIT. If I had
not had VEDIT I would have been REALLY miserable. VEDIT saved
my NECK.)
Now back to Search & Replace :-)
From Search & Replace v1.4,
it includes the ability to use
user-specified
setup files
-- so an administrator can copy the
main file to /usr/local/bin and give each user the ability
to use the script with their own setup variables, and file
extensions. File extension options now provide the ability
to 'include or exclude' files with a set of extensions, or
ignore extensions altogether. The command line options still
work, of course.
[ Note to Programmers: If you're a programmer,
and are concerned about issues such as 'use strict', 'my'
and other programming constructs, you may be interested in a note about
programming methods. ]

What's New & Change Log
- v1.4 - October 27, 2001
. moved 'values in text file' to external include file,
to allow multiple users to use that feature.
The thought behind specifying variables in an include file
was that complicated regexes might be easier in a file,
rather than on the command line.
. created a variable for the default include file name.
. modified the parameter for a user specified include file name
. removed the -h parameter for HELP
. changed -u (for 'values in text file') to -d
. Now, -d pulls in the default include file name, or
<filename> (one parameter) pulls in a user specified file
. added input parameters to deal with file extensions
-include, -exclude, -ignore [default= -include]
=> include means 'include files with these extensions'
=> exclude means 'exclude files with these extensions'
=> ignore means 'ignore the extension and process all
files'
-FILENAME [default= -none (use internal extension
array if no file)]
. modified the help and prompt screens
- v1.3 - May 9, 2001
. added output of actual replaces to 'sr.replaces.log'
. changed the formal name to 'Search and Replace'
. changed the file name to 'srep.cgi' (for stability)
- v1.2 - May 6, 2001
. Initial Public Release.
. Changed to line method of parsing.
. Added prompts, recursive directories, logs,
essentially a complete rewrite.
- v1.0 - May 20, 1998
. Initial release. Used 'chunk' method of parsing text,
instead of lines
. Only operated on one file at a time
