Execute another awk from awk file

Question

Is it possible to execute another awk file from a awk file? Using an awk file I need to execute all awk files in a current folder. Is it possible to do such operations in awk?

Answer 1

Yes you can. You'll need to use the system() function. I'm assuming you only want to run these scripts once. If so, you can add them to the BEGIN block of your wrapper script:

BEGIN {
    system("awk -f ./script1.awk")
    system("awk -f ./script2.awk")
    system("awk -f ./script3.awk")
}

If you have a large number of scripts that need to be executed, you can use a for loop. Do make sure that your wrapper script isn't in the same directory as all the other awk scripts you'd like executed, or it will be included in the glob of awk scripts...

BEGIN {
    system("for i in *.awk; do awk -f \"$i\"; done")
}
