.Dd June 6, 2007 .Dt PROGRESS 1 .Os .Sh NAME .Nm progress .Nd feed input to a command, displaying a progress bar .Sh SYNOPSIS .Nm .Op Fl ez .Op Fl b Ar buffersize .Op Fl f Ar file .Op Fl l Ar length .Op Fl p Ar prefix .Ar cmd .Op Ar args ... .Sh DESCRIPTION The .Nm utility opens a pipe to .Ar cmd and feeds an input stream into it, while displaying a progress bar to standard output. If no filename is specified, .Nm reads from standard input. Where feasible, .Nm .Xr fstat 2 Ns s the input to determine the length, so a time estimate can be calculated.
p If no length is specified or determined, .Nm simply displays a count of the data and the data rate.
p The options are as follows: l -tag -width XlXlengthXX t Fl b Ar buffersize Read in buffers of the specified size (default 64k). An optional suffix (per .Xr strsuftoll 3 ) may be given. t Fl e Display progress to standard error instead of standard output. t Fl f Ar file Read from the specified .Ar file instead of standard input. t Fl l Ar length Use the specified length for the time estimate, rather than attempting to .Xr fstat 2 the input. An optional suffix (per .Xr strsuftoll 3 ) may be given. t Fl p Ar prefix Print the given .Dq prefix text before (left of) the progress bar. t Fl z Filter the input through .Xr gunzip 1 . If .Fl f is specified, calculate the length using c gzip -l . .El .Sh EXIT STATUS .Ex -std .Sh EXAMPLES The command .Dl progress -zf file.tar.gz tar xf - will extract the
a file.tar.gz displaying the progress bar as time passes: d -literal 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 .Ed
p If it is preferred to monitor the progress of the decompression process (unlikely), then .Dl progress -f file.tar.gz tar zxf - could be used.
p The command .Dl dd if=/dev/rwd0d ibs=64k | \e .Dl progress -l 120g dd of=/dev/rwd1d obs=64k will copy the 120 GiB disk .Sy wd0
a ( /dev/rwd1d ) , displaying a progress bar during the operation. .Sh SEE ALSO .Xr ftp 1 , .Xr strsuftoll 3 .Sh HISTORY .Nm first appeared in .Nx 1.6.1 . The dynamic progress bar display code is part of .Xr ftp 1 . .Sh AUTHORS .Nm was written by .An John Hawkinson .Aq jhawk@NetBSD.org . .Xr ftp 1 Ns 's dynamic progress bar was written by Luke Mewburn. .Sh BUGS Since 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 .Nm itself.
