    Yeah, it’s a pain. Leads to bad one liners:

    for i in $(ls); do zcat $i || cat $i; done

        Won’t this cause cat to iterate through all files in the cwd once zcat encounters an issue, instead of just the specific file?

          Yeah, i was tired and had $file there first, then saw that you wanted to cat all in directory. Still tired, but i think this works now.

        You can just do for f in * (or other shell glob), unless you need find’s fancy search/filtering features.

        The shell glob isn’t just simpler, but also more robust, because it works also when the filename contains a newline; find .. | while read -r will crap out on that. Also apparently you want while IFS= read -r because otherwise read might trim whitespace.

        If you want to avoid that problem with the newline and still use find, you can use find -exec or find -print0 .. | xargs -0, or find -print0 .. | while IFS= read -r -d ''. I think -print0 is not standard POSIX though.

      Thanks !

      But still we shouldn’t have to resort to this !

      Also, can’t get the output through pipe

      for i in $(ls); do zcat $i || cat $i; done | grep mysearchterm

      this appears to work

      find . -type f -print0 | xargs -0 -I{} sh -c 'zcat "{}" 2>/dev/null || cat "{}"' | grep "mysearchterm"

      Still, that was a speed bump that I guess everyone dealing with mass compressed log files has to figure out on the fly because zcat can’t read uncompressed files ! argg !!!

      for i in $(ls); do zcat $i 2>/dev/null || cat $i; done | grep mysearchterm

    just use -f lol.

    less $(which zcat) shows us a gzip wrapper. So we look through gzip options and see:

    -f --force
    Force compression or decompression. If the input data is not in a format recognized by gzip, and if the option --stdout is also given, copy the input data without change to the standard output: let zcat behave as cat.
