NAMEprogress — feed input to a command, displaying a progress bar
|progress||[-ez] [-b buffersize] [-f file] [-l length] [-p prefix] cmd [args ...]|
DESCRIPTIONThe progress utility opens a pipe to cmd and feeds an input stream into it, while displaying a progress bar to standard output. If no filename is specified, progress reads from standard input. Where feasible, progress fstat(2)s the input to determine the length, so a time estimate can be calculated.
If no length is specified or determined, progress simply displays a count of the data and the data rate.
The options are as follows:
- -b buffersize
- Read in buffers of the specified size (default 64k). An optional suffix (per strsuftoll(3)) may be given.
- Display progress to standard error instead of standard output.
- -f file
- Read from the specified file instead of standard input.
- -l length
- Use the specified length for the time estimate, rather than attempting to fstat(2) the input. An optional suffix (per strsuftoll(3)) may be given.
- -p prefix
- Print the given “prefix” text before (left of) the progress bar.
- Filter the input through gunzip(1). If -f is specified, calculate the length using gzip -l.
EXIT STATUSThe progress utility exits 0 on success, and >0 if an error occurs.
will extract the file.tar.gz displaying the progress bar as time passes:
progress -zf file.tar.gz tar xf -
0% | | 0 0.00 KiB/s --:-- ETA 40% |******** | 273 KiB 271.95 KiB/s 00:01 ETA 81% |*********************** | 553 KiB 274.61 KiB/s 00:00 ETA 100% |*******************************| 680 KiB 264.59 KiB/s 00:00 ETA
If it is preferred to monitor the progress of the decompression process (unlikely), then
could be used.
progress -f file.tar.gz tar zxf -
dd if=/dev/rwd0d ibs=64k | \
will copy the 120 GiB disk wd0 (/dev/rwd0d) to wd1 (/dev/rwd1d), displaying a progress bar during the operation.
progress -l 120g dd of=/dev/rwd1d obs=64k
HISTORYprogress first appeared in NetBSD 1.6.1. The dynamic progress bar display code is part of ftp(1).
AUTHORSprogress was written by <jhawk@NetBSD.org>. ftp(1)'s dynamic progress bar was written by Luke Mewburn.
BUGSSince the progress bar is displayed asynchronously, it may be difficult to read some error messages, both those produced by the pipeline, as well as those produced by progress itself.
