To uncompress bzip2'd files on the fly, i.e. to be able to use "less"
on them without first bunzip2'ing them, you can make a lesspipe.sh (man
less) like this:
#!/bin/sh
# This is a preprocessor for 'less'. It is used when this environment
# variable is set: LESSOPEN="|lesspipe.sh %s"
case "$1" in
*.tar) tar tvvf $1 2>/dev/null ;; # View contents of various tar'd files
*.tgz) tar tzvvf $1 2>/dev/null ;;
# This one work for the unmodified version of tar:
*.tar.bz2) bzip2 -cd $1 $1 2>/dev/null | tar tvvf - ;;
#This one works with the patched version of tar:
# *.tar.bz2) tyvvf $1 2>/dev/null ;;
*.tar.gz) tar tzvvf $1 2>/dev/null ;;
*.tar.Z) tar tzvvf $1 2>/dev/null ;;
*.tar.z) tar tzvvf $1 2>/dev/null ;;
*.bz2) bzip2 -dc $1 2>/dev/null ;; # View compressed files correctly
*.Z) gzip -dc $1 2>/dev/null ;;
*.z) gzip -dc $1 2>/dev/null ;;
*.gz) gzip -dc $1 2>/dev/null ;;
*.zip) unzip -l $1 2>/dev/null ;;
