UNIX for Advanced & Expert Users

Hello colleagues,
In AIX there is the option -p in grep command , what is the equivalent in linux RedHat?

regards

What does -p do in AIX? I stared at the manpage a while but couldn't make sense of it, and I don't have an AIX machine to test with.

It has something to do with paragraphs, that much I can tell. awk can be used in such a manner -- considering some pattern other than \n to be a record separator.

Don't think linux version of grep has exact match for that option, but check out this info:
regex - How to find patterns across multiple lines using grep? - Stack Overflow
HowTo: grep Text Between Two Words in Unix / Linux

This Funcionality is in AIX:
grep Command

p[Separator] Displays the entire paragraph containing matched lines. Paragraphs are delimited by paragraph separators, as specified by the Separator parameter, which are patterns in the same form as the search pattern. Lines containing the paragraph separators are used only as separators; they are never included in the output. The default paragraph separator is a blank line.

Code:

awk -v RS="" '/regex/' inputfile
