Top Forums Shell Programming and Scripting Script Works But Need It to Exit Upon Closing Program Post 303031830 by jakefish on Wednesday 6th of March 2019 09:47:04 AM

@Chubler_XL--thank you for the idea

Code:
while pgrep --session 0 links

I ran that in both the Chrome and Links2 scripts, but the script does continue to spawn itself, with a maximum of three instances, usually running two instances.

But the modifier was new to me and I was glad to learn about it.

As for my ampersand query, thank you, RudiC:

>> it seems that unless told otherwise these commands will work on the last (highest) window on "stack" <<

Makes sense to me. It's intriguing that

Code:
xlinks2 &

can send xlinks2 to the background, but subsequent xlinks2 commands (window maximization, key strokes, etc) act as if xlinks2 is in the foreground, or at least physically visible. It would appear that background vs foreground features of a script are not literal, meaning that a given background process can actually be the one thing you're seeing.

NAME
Flush - GTK-based BitTorrent client SYNOPSIS
flush [OPTIONS] [TORRENT_FILE]... DESCRIPTION
Flush is a GTK-based BitTorrent client. You can use it to download files from the BitTorrent network. You can control already running instance, for example, by following commands: flush -o --download-rate-limit=100 flush --start=all FEATURES
* Controlling running instance by command line interface, such as: * Starting/stopping torrents. * Changing download/upload rate limit. * Changing maximum connections limit. * Running many instances with different configs from the same user. * Automatic copying finished downloads to specified directory. * Setting custom download path for each file of the torrent. * Ability to choose torrent file's character set encoding. * Automatic torrents loading from specified directory. * Automatic pausing and removing old torrents. * Temporary pausing and resuming torrents. * Overall and current session statistics. * Creating your own torrent files. * IP filter. OPTIONS
--version Show program version and exit. --help Show help options and exit. --config=DIRECTORY Configuration directory path (default: ~/.flush). --download-rate-limit=SPEED Set download rate limit (KB/s). --upload-rate-limit=SPEED Set upload rate limit (KB/s). --max-uploads=NUMBER Set maximum uploads. --max-connections=NUMBER Set maximum connections. --start={all,downloads,uploads} Start torrents. --stop={all,downloads,uploads} Stop torrents. -o, --only-pass Only pass commands to already running Flush instance. Does not start new instance if it is not running yet. FILES
~/.flush Default configuration directory. BUGS
On startup Flush finds already running instances via DBus session bus. Therefore it is necessary to run Flush in a single session bus (usual in X session bus) to prevent running several instances with one configuration path. Please notice that when you are running Flush from console or by cron, when DISPLAY environment variable is not available, Flush finds already running GUI instance without problems via ${config_path}/dbus_session link, which all GUI instances are creating when they have owned DBus name. This makes it possible to control running Flush GUI instances from cron. AUTHOR
