#awk If else loop not working in ksh

I have code where awk is piped to a clearcase command where If else loop is not working.

code is below :

#!/bin/ksh    
export dst_region=$1    
cleartool lsview -l | gawk -F":" \ '{ if ($0 ~ /Global path:/) { if($dst_region == "ABC" || $dst_region -eq "ABC") { system("echo dest_region is ABC");} 
else { system("echo dest_region is not ABC"); } }; }'

But when I execute the above script the I get incorrect output,

*$ ksh script.sh ABCD

dest_region is ABC

$ ksh script.sh ABC 

dest_region is ABC*

Could anyone please help on this issue ?

Solution

  • It would be useful if you explained exactly what you are trying to do but your awk script can be cleaned up a lot:

     gawk -F":" -vdst_region="$1" '/Global path:/ { if (dst_region == "ABC") print "dest_region is ABC"; else print "dest_region is not ABC" }'

    General points:

    • I have used -v to create an awk variable from the value of $1, the first argument to the script. This means that you can use it a lot more easily in the script.
    • awk's structure is condition { action } so you're using if around the whole one-liner unnecessarily
    • $0 ~ /Global path:/ can be changed to simply /Global path:/
    • the two sides of the || looked like they were trying to both do the same thing, so I got rid of the one that doesn't work in awk. Strings are compared using ==.
    • system("echo ...") is completely unnecessary. Use awk's built in print

    You could go one step further and remove the if-else entirely:

     gawk -F":" -vdst_region="$1" '/Global path:/ { printf "dest region is%s ABC", (dst_region=="ABC"?"":" not") }'
