What i am doing is , i tail a file from certain chatacter and then cat -n to get the line numbers.I search for a particular string and gets it line number. What i am interested in is the next line immediately after the pattern i search.
But grep gives me result for all line statring with those digits.
For Ex:
I got the pattern in line as:
10 Pattern i searched.
Now, I need contents of line 11(i store in variable say $next_line).
so i do :
But it gives me result for the lines like 11, 111, 110 and so on .
Is there a way to only search for the exact number in grep.

I want to grep from a file an exact character match.
I tried grep -c "$a $b" $file
where a=6 and b=2
the problem is that I get: 6 2 and 6 20
I just need a count of the occurrence.
I'm using the Bourne shell.
I've also tried grep -c '$a $b' $file;
not sure how to do this - any suggestions? (3 Replies)

zegrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
