different take on common ?: search for two strings and remove lines between them

laser · #1 (**permalink**) 12-03-2008

Thank you for assisting,

I've got a partial solution just needs a tweak.

Code:

Hulk-BASH$ cat somefile.txt
oh there is some stuff here
some more stuff here
START_LABEL
stuff I want
more stuff I want
END_LABEL
other stuff here too
and even more stuff here too
Hulk-BASH$

Hulk-BASH$ sed -n '/^START_LABEL/,/^END_LABEL/p' somefile.txt
START_LABEL
stuff I want
more stuff I want
END_LABEL
Hulk-BASH$

Code:

cat test | awk -F 'START_LABEL' 'BEGIN{RS="END_LABEL"; OFS="\n"; ORS=""} {print $2}'

Thank you Ikon, but I received this:

Code:

Hulk-BASH$ cat somefile.txt | awk -F 'START_LABEL' 'BEGIN{RS="END_LABEL"; OFS="\n"; ORS=""} {print $2}'
awk: syntax error near line 1
awk: bailing out near line 1
Hulk-BASH$

Try this:

Code:

awk '/^START_LABEL/{p=1;next}/^END_LABEL/{exit}p' file

Wow I wonder what is up, still same errors, I'm using Solaris
Thx Franklin

Code:

Hulk-BASH$ awk '/^START_LABEL/{p=1;next}/^END_LABEL/{exit}p' somefile.txt
awk: syntax error near line 1
awk: bailing out near line 1
Hulk-BASH$

as always on Solaris, use 'nawk' instead of 'awk'.

Hi,

sed is fine, simply add some characters, e.g.:

Code:

sed -n '/^START_LABEL/,/^END_LABEL/{/LABEL$/!p}' somefile
