PROGRESS(1)						    BSD General Commands Manual 					       PROGRESS(1)

NAME

     progress -- feed input to a command, displaying a progress bar

SYNOPSIS

     progress [-ez] [-b buffersize] [-f file] [-l length] [-p prefix] cmd [args ...]

DESCRIPTION

     The progress utility opens a pipe to cmd and feeds an input stream into it, while displaying a progress bar to standard output.  If no file-
     name is specified, progress reads from standard input.  Where feasible, progress fstat(2)s the input to determine the length, so a time esti-
     mate 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.

     -e 	  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.

     -z 	  Filter the input through gunzip(1).  If -f is specified, calculate the length using gzip -l.

EXIT STATUS

     progress exits 0 on success.

EXAMPLES

     The command
	   progress -zf file.tar.gz tar xf -
     will extract the file.tar.gz displaying the progress bar as time passes:

       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
	   progress -f file.tar.gz tar zxf -
     could be used.

     The command
	   dd if=/dev/rwd0d ibs=64k | 
	   progress -l 120g dd of=/dev/rwd1d obs=64k
     will copy the 120 GiB disk wd0 (/dev/rwd0d) to wd1 (/dev/rwd1d), displaying a progress bar during the operation.

HISTORY

     progress first appeared in NetBSD 1.6.1.  The dynamic progress bar display code is part of ftp(1).

AUTHORS

     progress was written by John Hawkinson <jhawk@NetBSD.org>.  ftp(1)'s dynamic progress bar was written by Luke Mewburn.

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 progress itself.
