i know 2 simple tools purpose:

  1. the tool zenity allows create gui progress bar shell script, e.g. zenity --progress --auto-close. zenity preinstalled on many linux systems. tool starts, , shows gui progress bar, while on stdin expects percentage of completion. e.g.:

    seq 0 20 100 | while read x; sleep 1; echo $x; done |    zenity --progress --auto-close

  2. the pv tool ("pipe viewer") can used replacement cat perk shows progress bar in text mode indicating amount/speed of data passing through pv. 1 has install it, not preinstalled. example, add progress bar decompression of large archive:

    pv large.tar.bz2 | tar -xjf -
