如何在不解压的情况下找到tar文件中文件的行数

Question

I have a tar file, which has lots of csv files in it. Is there a way to find the number of lines in each csv file without extracting it in linux?

I tried

for file in $(tar -tf "$tarfile")
do
  NL=`wc -l < "$file"`
done

But it gives error: "No such file or directory".

Can anyone help please.

Answer 1

Try this:

for file in $(tar -tf "$tarfile")
do
    NL=$(tar Oxf "$tarfile" "$file" | wc -l)
done

Oxf extracts the specified file to stdout.
