hi,
grep -A is not working for HP unix.
$ grep -A 10 "ARMP" tnsnames.ora
grep: illegal option -- A

please let me know is there any other option?
Thanks.

Will a shell script do for you? I don't know if it can be done using some command.

probably an easier way to do this but, this works....

Code:
#  sed -ne '/string/{
n
p
n
p
n
p
n
p
n
p
n
p
n
p
n
p
n
p
n
p
}
' infile
