Calling shell script within awk script throws error

Shell Programming and Scripting
1

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: `./billdatecalc.sh <SetList>50/10000////D4B790E1////3/0</SetList>'

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

awk '
                
                /SetList/ {
                                param = $0
                                cmd = "./billdatecalc.sh "$param""
                                system(cmd)
                }
' touch.xml

too many qoutes:

cmd = "./billdatecalc.sh \"$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...

5

Also awk variables are not referenced with a dollar sign $

Try this:

param = $0
cmd = "./billdatecalc.sh " 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 = "./billdatecalc.sh " param

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

param="<SetList>5/315/3///////NONE/0</SetList>"

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

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

cmd = "./billdatecalc.sh \"<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

Try

cmd="./billdatecalc.sh " param

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

It doesn't make any difference as I am still getting the syntax error

sh: -c: line 0: syntax error near unexpected token `newline'

What is your OS and version?
What is in billdatecalc.sh ?
What happens when you use

cmd="echo xxx " param

Does it work then?

OS and version is

Linux 2.6.9-67.ELlargesmp #1 SMP Wed Nov 7 14:07:22 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

The shell script reads the input parameter being passed, checks for a particulat pattern and if found replace that pattern with a different value.

billdatecalc.sh

I tried this code

cmd="echo xxx " param

and still the same syntax error

What does

cmd="./billdatecalc.sh \"" param "\""

produce?
Otherwise could you post billdatecalc.sh

--edit--
OK you say even cmd="echo xxx " param produces the wrong results, odd..
