linux_shell_kit

Random Linux shell stuff.

This repository contains my random Linux shell stuff, including:

  • The utility libraries
  • The tools

The utility libraries

t_util_lib.sh

  • Data size conversion (e.g: from gibibytes to bytes)
  • Echo with prefix

The tools

t_proc_info.sh

Provides brief info of a process by using existed tools (top, lsof...) and displays results in a visual, organized manner.

Output example:

$ ./t_proc_info.sh 39614
