Passing multiple files to awk for processing in bash script
Hi,
I'm using awk command in bash script. I'm able to pass multiple files to awk for processing.The code i can use is as below(sample code)
In the above code i'm passing the file names manually and it is fine till my processing files are less. Suppose if i have a 1000's of files in a directory, then how can i process them using awk at a time?
Can i point to a directory so that the awk will take all the files present in that directory and allowing me not to supply all the filenames to awk command?
Is it possible?
I have a directory full of zip files.
How would I write a bash script to enumerate all the zip files, remove the ".zip" from the file name, create a directory by that name and unzip each zip file into its corresponding directory?
Thanks!

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...

DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
