Bash, grep between a line with specified string till a character (not include) -

-

example:

> header abc , blablabla some_lines1 some_lines2 some_lines3 > header bcf , blablabla some_lines4 some_lines5 > header abc , blablabla some_lines6 >......

here want grep line 'abc' , lines after before '>', result should like:

> header abc , blablabla some_lines1 some_lines2 some_lines3 > header abc , blablabla some_lines6 > ...

since number of lines in between not fixed, can't apply grep -a i've tried using sed, doesnt work well:

sed -n '/abc/,/>/p' file

unwanted result:

> header abc , blablabla some_lines1 some_lines2 some_lines3 > header bcf , blablabla > header abc , blablabla some_lines6

another sed:

sed -n '/abc/,/>/{/abc/b;/>/b;p}' file

unwanted result:

some_lines1 some_lines2 some_lines3 some_lines6

you can use awk:

awk '/^>/{p=0} /abc/{p=1} p' file > header abc , blablabla some_lines1 some_lines2 some_lines3 > header abc , blablabla some_lines6
