SSWITCH
Free DOS utility: text file search and replace
Version 1.00 - July 14, 1993

SSWITCH searches for and replaces strings in text files. A string is any
sequence of up to 255 characters, and may contain spaces. Case is ALWAYS
sensitive, that is, David is not the same as david.
Usage: SSWITCH source_file new_destination_file
You must use the DOS command SET as follows:
SET switch_s=search_text
SET switch_r=replace_text
SSWITCH takes exactly two parameters on the command line, both of which are
both MANDATORY: the name of the file to search followed by a NEW file name,
which will be the altered file. (Wildcards are not allowed.)
SSWITCH also requires that two environmental variables be set:
switch_s (the text you are searching for) and
switch_r (the text you are replacing it with).
EXAMPLE: to replace the phrase "am disgusted with" with the word "enjoy"
(both without the quotes), in the file gripe.ltr, with the new file being
praise.ltr, the following three commands must be entered exactly as shown:
set switch_s=am disgusted with
set switch_r=enjoy
sswitch gripe.ltr praise.ltr
That's it!
Limitations: no string, including lines in the file, may ever exceed 255
characters. The program will work, but your lines will be truncated.
The program will not span lines when searching for text to replace, so
if searching this file for "255 characters" it will find on this line only.
