Even some implementations of ed may create a temp file.
It's never a good thing to edit your originals. If you screw up, you've lost data.

Hi Gurus,
I am working with a korn shell script. I should replace in a very great file the character ";" with a space.
Example:
2750;~
2734;~
2778;~
2751;~
2751;~
2752;~
what the fastest method is? Sed? Awk?
Speed is dead main point, Seen the dimensions of the files
Thanks (6 Replies)

NAME
espdiff - apply the appropriate transformation to a set of patches
SYNOPSIS
espdiff [--deep-brainwave-mode] [--recurse] [--compare] [file...]
espdiff {[--help] | [--version]}
DESCRIPTION
espdiff applies the appropriate transformation to a patch or set of patches, depending on what you intend to accomplish.
The input patches must be "clean": in other words they must apply without fuzz or offsets in whichever order they are meant to be applied.
The exception is if you intend espdiff to clean them for you (good luck).
You may find it useful to cross your fingers while the program performs its task, or to screw your eyes tight shut while imagining it doing
the right thing.
OPTIONS
--deep-brainwave-mode
Probes your brain deeply in a manner that takes longer, but produces better extra sensory results.
--recurse
Recurses neural pathways throughout all parts of the brain, in some cases determining code changes you might make far off in the
future. You may feel a gentle tickling sensation when using this option.
--compare
Allows the program to scan the current directory examining existing patches to determine areas of code you are likely to change again,
and concentrating on these areas more closely.
--help
Display a short usage message.
--version
Display the version number of espdiff.
LIMITATIONS
Do not use this program while sleep-walking, or before your first cup of coffee.
There are some cases in which it is not possible to determine what the intention of the user is. In these cases, you should construct the
output you desire using an editor, and send the input files together with the desired output file to Tim Waugh twaugh@redhat.com asking for
a new diff tool.
