Unpack functions and BSDProgress - progress bar for your archives.

A colored unpack script using bar:

A little KSH93 function for your .profile. Now you can augomatically unpack most archives while watching the pretty progress bar.

You need bsdprogress (Solaris and Linux port of NetBSD's progress). With a bit work it also works on AIX.

I just re-wrote this for progress, so I didn't check the cpio and such yet.

# Mihai Criveti - Unpack function:
# Progress Unpack - unpack using GNU tar and bsdprogress.
function up {
for archive in $*; do
  print $archive;
  case $archive in
       (*.tar) progress -f $archive gtar xpif - ;;
       (*.tar.gz) progress -f $archive gtar -zpixf - ;;
       (*.tgz) progress -zf $archive gtar -ipxf - ;;
       (*.tar.bz2) progress -f $archive gtar -jipxf - ;;
       (*.tbz) progress -f $archive gtar -jipxf - ;;
       (*.gz) progress -f $archive gunzip -;;
       (*.bz2) progress -f $archive bunzip -;;
       (*.tar.Z) uncompress -c $archive | tar gxvf - ;;
       (*.cpio) cpio -icd < $archive ;;
       (*.Z) uncompress $archive ;;
       (*.rar) unrar x $archive ;;
       (*.zip) unzip $archive ;;
  esac
done
}

Let's say we want to unpack files that end in *bz2 (it will automagically detect .tar.bz2 or tbz2), *gz and a specific tar archive:

See:

It builds fine on AIX (Makefile tweaks), Solaris and Linux. Native on NetBSD.
