Calling shell script within awk script throws error

I am getting the following error while passing parameter to a shell script called within awk script. Any idea what's causing this issue and how to ix it ? Thanks

sh: -c: line 0: syntax error near unexpected token `newline'
sh: -c: line 0: `./ <SetList>50/10000////D4B790E1////3/0</SetList>'

The "param" variable carries the following data "<SetList>50/10000////D4B790E1////3/0</SetList>"

awk '
                /SetList/ {
                                param = $0
                                cmd = "./ "$param""
' touch.xml

too many qoutes:
cmd = "./ \"$param\""

Thanks for the input. The syntax issue is solved. However I don't see any data being passed in the parameter and it always seems to be empty. Any idea ?

The system function if just for execution and only provides the return code, otherwise try using the "cmd" | getline construct instead...

Also awk variables are not referenced with a dollar sign $

Try this:
param = $0
cmd = "./ " param
cmd | getline var
close (cmd)
print var

Using this part of the code again leads to syntax error
sh: -c: line 0: syntax error near unexpected token `newline'

cmd = "./ " param

I tried this one , the syntax issue disappeared however no data being passed in variable "param".


cmd = "./ \"$param\""

I tried directly substituting the data directly as follows and the shell script is able to read the data being passed.

cmd = "./ \"<SetList>5/315/3///////NONE/0</SetList>\""

It appears that there is something wrong the way the variable being passed in the shell script

Any idea ? Thanks

cmd="./ " param

You may want to avoid using a relative path name...
