How to Read Multiple Files in a Loop ?

My input file having 10 ZIP files.

Happy Holidays.

I don't know what you mean by: "My input file having 10 ZIP files."
Assuming that you mean that you have ten Zip files in your current working directory all with names ending in .zip, you could try putting my earlier code in a loop something like:

Code:

for zip in *.zip
do	printf 'Processing Zip file "%s"\n' "$zip"
	unzip -Z1 "$zip" | while IFS= read -r file
	do	printf '%8d %s\n' "$(unzip -p "$zip" "$file"|wc -l)" "$file"
	done
done

If you mean that you have a file (in this example named ziplist.txt that contains pathnames of your Zip files with one Zip file on each line in that file, it would be something more like:

Code:

while IFS= read zip
do	printf 'Processing Zip file "%s"\n' "$zip"
	unzip -Z1 "$zip" | while IFS= read -r file
	do	printf '%8d %s\n' "$(unzip -p "$zip" "$file"|wc -l)" "$file"
	done
done < ziplist.txt

lzfgrep

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME

       xzgrep - search compressed files for a regular expression

SYNOPSIS

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION

       xzgrep  invokes	grep(1)  on  files  which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options
       specified are passed directly to grep(1).

       If no file is specified, then the standard input is decompressed if necessary and fed  to  grep(1).   When  reading  from  standard  input,
       gzip(1) and bzip2(1) compressed files are not supported.

       If  xzgrep  is  invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same applies to names lzgrep, lze-
       grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

       grep(1), xz(1), gzip(1), bzip2(1), zgrep(1)
