Need help with the syntax

[rogers42]

Hi,

I am working on an awk utility that manipulates the following two files

a, A file with a list of files (final.txt)

The contents of the "final.txt" files are as follows
./test_data/allstream_bss_cfg.xml
./test_data/ss_ma_bss_cfg.xml


b, A file with "search" and "replace" patterns (source_target_strings.txt)

The contents of the "source_target_strings.txt" file are as follows

47.150.56.224,47.150.56.999
16701,99999

PS: source and target strings are comma delimited


The idea here is to search & replace some IPs, host names etc from all the files.

My utility looks as follows

# awk script is invoked on each line of "final.txt"
# Search & replace strings
#
BEGIN { }
{ print $0

while( getline < "source_target_strings.txt")
{
# Extract the source and target strings
split($0, a, ",")
target = a[0];
source = a[1];

print a[0];
print a[1];
system("nawk '{/target/source/g }' $0");
}

close("source_target_strings.txt");
}

From the command line, I invoke the awk utility as follows

nawk -f reconfigure.awk final.txt

I need help with the syntax for passing the correct parameters (i.e. target, source, and file name) on the system call.

Thanks in advance.
