Need Help??

noviceuser has asked for the wisdom of the Perl Monks concerning the following question:

suppose i have multiple lines like below and i want to grep lines having "code" only after fixed pattern "/dir1/dir2/100.10/dir3/100.20/" . i have tried using grep "/code/",but it is giving all the lines containing the match elsewhere. please help

/dir1/dir2/100.10/dir3/100.20/code/abc/def.txt
/dir1/dir2/100.10/dir3/100.20/code/def/ghi.txt
.

What prevents you from grepping for `/dir1/dir2/100.10/dir3/100.20/code` then?	[reply] [d/l]

It's doing exactly what you're telling it to do since `code` (heh) is in the examples you. grep works conceptionally the same way as the utility, so you need to define a regexp that's sufficiently selective.	[reply] [d/l]
