Shell Programming and Scripting

I need to export the built in awk variables for columns so that they are available for the rest of the script. This is what I have so far:

Code:

cat /tmp/test | eval `awk '{print "export NAME="$1; print "export NAME2="$2;}'`
echo Host is "$NAME" and Host2 is "$NAME2"

When I run bash -x to debug, the variables do get assigned but then when the echo command runs they come up empty. I need to have these variables assigned so that the entire script can make use of them. Any ideas would be greatly appreciated.

One approach is redirect output to a file and source the file, so that variables can be used further:

Code:

awk ' { print "export NAME1="$1; print "export NAME2="$2 }' /tmp/test > source_vars

. ./source_vars

echo "Host is $NAME1 and Host2 is $NAME2"

Why use awk? Try:

Code:

read NAME NAME2 < /tmp/tst
export NAME NAME2

@bipinajith, you do not need to chmod +x if you only source a file..
