('progress' in Svenska, almost)
Vramsteg is an open source, command line utility that provides shell scripts with a full-featured progress indicator. The progress bar can display elapsed time, remaining time estimate, percentage completed, and labels. The progress bar can have user-specified colors, and be rendered in multiple styles.
See the man page (enter 'man vramsteg') for full details on how to use vramsteg or look in the examples directory for several shell scripts that illustrate usage.
