interactively and selectively kill a group of processes which match certain pattern

Intoduction

SelectKill is a simple bash script which interactively and selectively kills a group of processes matching certain pattern.

Usage

• download the repository

git clone https://github.com/Gyumeijie/SelectKill.git

• cd into the SelectKill, and run the following command

./install.sh

• now you can play with the SelectKill command

1. run SelectKill with a pattern

As shown above, all the processes match the pattern root will be displayed in the option region, you can use the up/down keys to select which process you want to kill.

2. select the process which requires root priviledge to kill

may you should try second time:

again, you can try the last time:

but if you failed for three times, SelectKill will give you the following message:

3. select the process which you have permission to kill

Say, you have the root priviledge and then you can kill the process with pid equavilent to 27237. Maybe you need to go through some steps talked above--typing your password.

Settings

The SelectKill has two regions: message region and options region. The message region is used to display information, say details of long option which is too long to display in the region; and the options region is to show information of processes matching the pattern, if one option is too long, we deprecate it at some point and replace the deprecated content with ... and when the long option is being selected we display the original information back in the message region.

set size for message region and options region

As shown in the picture above, we can customize the size of both regions in the config.ini file. Say we can have message region set to 4 rows and option region to 5 rows, the following is the corresponding setting:

  LISTNUM=5  # size of option region
  MSGNUM=4   # size of message region

set the duration of showing instant message

Instant messages like prompting successfully killing a process or being denied to kill a process should not be always shown in message region, so we can give them a duration for displaing, say 1.5 s, and when the duration is elapsed we show other messages. The following is the corresponding setting:

  SHOW_DURATION=1.5

set the initially selected option

We can also set the initially selected option, the default is not choosing any option in the region, but we can set it to, say, the first option or any other option. The following is the corresponding setting:

  INIT_SELECTED=-1

and any invalid value which is less than -1 or greater than the number of total options will be forcibly reset to the default -1.

Todos

• Prettify processes information shown in the option region.
• Support refreshing for getting realtime processes information but not a static snapshot.
• Add confirming session for killing a process.
