[SOLVED] File having lines in which contain "-TP_" word : Only Those words needed

Nice; can you make it work for the 1st field per line?

As far as I know, sed does not support non-greedy matching, so not using the same approach, but if you have two seds chained together, it can usually* be converted to a single sed:

Code:

sed -ne 's/\([A-Z]*-TP_[A-Z]*\).*/ \1/' -e 's/.*[^A-Z]\([A-Z]-TP_\)/\1/p'

* Theoretically it can always be converted, but sometimes the resulting sed script may be quite complicated and not worth it.

Yeah, I got a 2 pass soln already (see my 1st post).
I was just wondering if a sed expert could come up with a single pass, just for my own edification.

Hi All,

ABCD-TP_XYZ CrossConnect RTQ TL5 STC NONE
Tpcx LMPI-TP_UIP CrossConnect RTQ TL0 STC NONE (LMPO-TP_UIP)
Tpc MPLO-TP_KP CrossConnect RTQ TL0 STC NONE (MPLO-TP_KP)

With all suggested methods I tried the code in Cygwin terminal and I found that is working fine but when I tried with TELNET due to Special Character it is showing error.

------------------------------------------------------------------------------
e.g following command give me error due to "~".
awk '{for (j=1;j<=NF;j++) if ($j~"-TP_") {print $j;break}}' $InFile >$OutFile
------------------------------------------------------------------------------
Has any one give me simple method in which there is no use of special character, That would be work for me on TELNET.

Well, the best way is to put (edit) whichever method you want to use into a file on the remote system, then run it.
That way you don't have to keep typing it in.
Alternately, put it into a file locally and scp it across.
You really shouldn't use telnet anyway, its all plaintext, so insecure; try ssh instead.
