Shell Programming and Scripting

Use gawk, nawk or /usr/xpg4/bin/awk on Solaris.

Try with other versions of awk like nawk , gawk .

when i am running

Code:

echo "aa (0124)-23456 bb" | awk '{printf("%s %s %s\n", $1,$2,$3)}'

it is giving the correct output

one more thing it is not removing all the special characters in the field like * & etc.

Something like that :

Code:

^$ > echo "aa *&+|(0124)-23456 bb" | awk '{gsub(/[^[:alnum:]]*/,"",$2); print $1 $2 $3}'
aa012423456bb
$

i tried with

Code:

 
echo "aa *&+|(0%124)-23456#$@!+= bb" | nawk '{gsub(/[^[:alnum:]]*/,"",$2); print $1 $2 $3}'

the expected output is 012423456
but the output that is coming is aabb

plz help
