But, i need to know how to do it in Sed or awk. i did the following codes to get my results. it is a two-stage work:
1) i changed the third "." to other unique char (#) and save in a temporary file (out1)
then, i deleted the values between the patterns
where out2 is the final output. I got the right output but, i want a sed or awk code that only one liner as your perl. Thanks
If the file uses a tab delimiter and there is only 1 per line:
That isn't portable sed, because \t is primarily a GNU extension. However, if it worked for you, and you only care about that platform, it should suffice.
I want to delete lines like this
sed '/FROM_HERE/,/TO_HERE/d'
but I would like to *not* delete the second match, i.e. the TO_HERE line. How can I achieve this?
Thank you! (1 Reply)

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
