Informations about the package pv-php
pv - monitor the progress of data through a pipeline
Description
Monitor progress of transfer of large archives, DB backup/restore, etc.
A pure PHP implementation of the pv
CLI tool. Useful in case of shared web hostings when you have SSH access, but cannot install packages.
Quoting original pv
's manual:
pv shows the progress of data through a pipeline by giving information such as time elapsed, percentage completed (with progress bar), current throughput rate, total data transferred, and ETA.
To use it, insert it in a pipeline between two processes, with the appropriate options. Its standard input will be passed through to its standard output and progress will be shown on standard error.
pv will copy each supplied FILE in turn to standard output (- means standard input), or if no FILEs are specified just standard input is copied. This is the same behaviour as cat(1).
Usage
A subset of options of original pv
is supported. The aim is to eventually become fully compatible.
-s SIZE
/ --size SIZE
- assume SIZE bytes to be transferred, for purposes of ETA and completion percentage calculation. Supports 'K' / 'M' / 'G' / 'T' suffix to specify larger units (IEC standard - multiplies of 1024).
-i INTERVAL
/ --interval INTERVAL
- udate display at about INTERVAL seconds. Decimal values are supported. Default: 0.2 seconds.
