Thank you both. Note however that you really should not rely on gzip's -l option, due to the format-imposed limit an input of size 4TiB or larger, the size reported by --list (-l) will be reduced modulo 2^32, i.e., "wrong". https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=149775#10 If at all possible, I suggest that you switch to a superior format/tool like lzma/xz. Not only do options like --list work as expected with .xz files, but you'll find the actual compression ratios are far higher.
