Hello,
I have never ever seen below notation for string substitution.
The strange thing for me is the position of the apostrophe. Should it be before the / or after the g?
If I had been writing that command line, I would have chosen below way:
Could you please explain what it differs...
Is that about the operating system?
Many thanks
Boris
Regular expressions uses meta-characters. These are characters that have special meaning beyond the representation of the character. The shell has also meta-characters. Therefore in order to protect the meaning of these characters it must be quoted so it gets passed to sed as the regular expression intended.
In this case the quoting could be avoided all together sed s/tttt/pppp/g /var/bin/czech.sh since there are no meta-characters.
Hello,

I'm drawing a blank on how to use sed to replace selectively based on position in the string (vs nth occurence):
hello.|there.|how.|are.|you.|
I want the period removed in the 3rd item (as defined by the pipe delimiter) if a period is present. So the result in this case would be:

LEARN ABOUT DEBIAN
fixnt
fixnt(1) Debian fixnt(1)NAME
fixnt - Filter for the Windows NT postscript printer driver.
SYNOPSIS
fixnt < BADFILE.ps > GOODFILE.ps
DESCRIPTION
The Windows NT postscript driver has a tendency to make broken postscript files, that are incompatible with psutils. fixnt is a filter
that fixes these problems, allowing the use of psnup(1).
The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout. It has no other form for invocation
and takes no options on the command-line.
OPTIONS
fixnt takes no options.
BUGS
fixnt does not check for NTPSOct94. For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
sed 's/NTPSOct94/NTPSOct95/g'
This is particularly important for Windows NT 3.5 users.
AUTHOR
fixnt was written by Holger Bauer <Holger.Bauer@topmail.de>, Michael Rath <rath@itsm.uni-stuttgart.de>, and Akim Demaille
<demaille@inf.enst.fr>.
REPORTING BUGS
Report bugs to the Authors, but avoid sending large postscript files.
Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
