need assistance with awk using system in Solaris

Trying to get more familiar with awk, and am using system command to scp a bunch of files across servers.

So I tried this, but it doesn't work. Does not error, just doesn't do anything.

ls *.dmp | awk ' {system("nohup scp "$1" username@server:/server/file/path/ &")}'

However, this works

ls *.dmp | awk ' {print "nohup scp "$1" username@server:/server/file/path/ &"}' > scp.sh && chmod +x scp.sh && ./scp.sh

Goal is just trying to execute everything that awk returns.

Solaris 10's /usr/bin/awk doesn't have a system function, and it will not raise an error when you make a call to an undefined function; the return value of the function will be whatever its argument is. Instead, use either /usr/xpg4/bin/awk or nawk.

As Glenn and Andrew pointed out, if all you need to do is run a shell command multiple times with one argument varying each time, this can be done in the shell itself without getting awk involved.

for f in *.dmp
do
    nohup scp "$f" username@server:/server/file/path/ &
done
