Hi,

Pls check if the below one helps you!

flag=`nawk '($1 ~ "1212") && ($2 ~ "1230") {flag=1; print flag}' test`

echo $flag will yield you the answer "1" after satisfying the awk conditions.

where contents of the file, "test" is as follows:

---------test-------------
1212 1230 1234 8456
1212 3434 7323 5640
--------------------------

However as far as i know, you cannot pass any awk variable to its parent shell. You need to assign it to a shell variable and then source it in your script.

Hope it helps.

rgds,

Srini

shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...] DESCRIPTION
This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found. OPTIONS
The following command line options are available. -s, --suppress Supress output. Useful to only test whether a program exists with the help of the return code. -r, --reverse Transform a forward path to a subdirectory into a reverse path. -d, --dirname Output the directory name of str. -b, --basename Output the base name of str. -m, --magic Enable advanced magic search for ""perl"" and ""cpp"". -p, --path path Search in path. Default is to search in $PATH. EXAMPLE
# shell script awk=`shtool path -p "${PATH}:." gawk nawk awk` perl=`shtool path -m perl` cpp=`shtool path -m cpp` revpath=`shtool path -r path/to/subdir` HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken over into GNU shtool. SEE ALSO
