Append file name to the beginning of each line
I want to append file names at the beginning of a line for each row

file content
Code:
abc.txt.gz 123|654|987
bcd.txt.gz 876|trf|kjh

I want a single output file with below format
Code:
abc.txt.gz|123|654|987
bcd.txt.gz|876|trf|kjh


This one is working but only with unzip files,need to have something like this working with zip files as i cannot unzip the files ...


Code:
awk '{print FILENAME ?"|" $0}' ${file}

gzip applies data compression algorithm to compress the file and it is not readable unless your decompress it. How do you expect to read the content of a gzip file without gunzip-ing it?

So you have to gunzip it and then apply your awk code.

If you don't want to unzip your file and achieve this, then you can use gzcat command:-

Code:
gzcat abc.txt.gz | awk -v fname="abc.txt.gz" '{print fname "|" $0}'

If you just want to replace the space with a "|" in the example file you posted:
Code:
$ cat t
abc.txt.gz 123|654|987
bcd.txt.gz 876|trf|kjh

$ sed 's/ /|/' t
abc.txt.gz|123|654|987
bcd.txt.gz|876|trf|kjh
