Bug#593260: ITP: bar -- Show information about a data transfer
Hello Michael, Michael Peek a écrit : I had no idea that pv existed. I took a look at it, and they are very similar. There are a few things that bar offers over pv: - ANSI color support - Configurable progress bar characters In the manpage I only found the option display-twiddle about it; are there other options for configuring characters? - Configurable I/O select() timeout - Ability to use configuration file(s) This feature is great. - Displaying of additional blocks of text read from a file during I/O - think information to display to the user during file installation - that are updated automatically throughout the I/O process (version 1.11.0, yet to be released) That one will be great too. The version which I can package now is 1.10.9 But there are also features in pv that bar lacks: -n, --numeric - Numeric output suitable for piping to dialog This feature may be important, I planned to use a regexp filter to parse bar's output, configuring bar to output easier parsed data would be great. -W, --wait - Wait until the first byte has been received before printing anything ... and before deciding that the input stream is closed. This feature can be approximately reached by setting a long timeout without modifying bar's source. -l, --line-mode - Instead of counting bytes, count lines -R, --remote - Communicate with another instance of pv to modify it's state For what it's worth, Michael Peek I shall reopen the ITP bug and upload the package.

Don Armstrong a écrit : [as a handfull of other vigilant developers] How does this [bar] differ from pv? h... I used Michael Peek's bar for a few years because I never heard about pv. Thank you for this notice. When I read pv's manpage, it appears as more featureful than bar. I use currently bar to monitor the cloning of USB sticks, as a replacement of dd to dump 4GB of an image into a flash memory driver. Is pv able to do the same? for example how can I use pv to monitor the transfer which is done by modifying a command such as: dd if=someImageFile of=/dev/disk/by-id/usb-TheNiceStick_0878101B77D1D977-0:0 with bar, the replacement would be: bar -s 4G -if someImageFile -of /dev/disk/by-id/usb-TheNiceStick_0878101B77D1D977-0:0 Best regards, Georges. signature.asc Description: Digital signature

Thank you for all the feedback about pv (and bar). I shall close this bugreport and I won't upload bar. Best regards, Georges.
