what is the output you are expecting in the sample you provided?

Y only "perl" and not others? sed,awk , normal bash etc?

Are you expecting a script that you can supply 2 arguments to:
Code:
my_script.pl user_data.dat  nusage.py

which returns all users with nusage.py in their values list?
Code:
~/ $ perl -e 'open DATA , "<", "tmp.dat";while(<DATA>){ if (/^user\s+(\d+)$/){ $uid=$1;}if(/$ARGV[0]/){print "user $uid matches\n"}}' gusage.py
user 11 matches
~/$

I think the TS meant "or" instead of "and":
Code:
perl -lne '/content is:|usage\.py/ && print' INPUTFILE
content is:
musage.py
content is:
gusage.py

I know how to do in sed by using hold buffer, but i want it in perl. I dont want to supply as command line arguments.

Output should be: user 10 or user 11.

I should search for "content is:" and musage.py it should print user 10.
similarly if I search for "content is:" and gusage.py it should print user 11.
Yes I know for this I may need two if loops.

Please let me know

Try:
Code:
perl -00 -ne '/content is:/ && /usage.py/ && /.*/ && print "$&\n"' INPUTFILE

actually file is

Quote:
intro
global: user 10
values
content is:
musage.py
yes
value

intro
global: user 11
values
content is:
gusage.py
yes
value
I want "content is:", "usage.py" and "global" to be searched but "global: user 10" and "global: user 11" should be printed.

Above one liner is not working if the file is like this.
Please let me know..
