Today, I learned a little bit about the shell programming under Linux and simply recorded the test cases.1. Edit the shell script file as follows:#!/bin/bashecho "Hello Bash Linux"echo "No. 0 parameter: $ A"echo "First parameter: $ $"echo "Current child shell process: $$"#pidarr = ' PS x | awk ' {print '} 'pidarr=$ (ps x | awk ' {print $} ')Echo $pidaddFor

process that waits for a CPU to process may contain many priority processes, but Linux is the operating system of a preemptive scheduling algorithm, which means that the highest-priority process execution must be found when scheduling. The above bitmap_size value is calculated according to Max_prio 5, then bitmap is a

control the process's access to the file.Note that the ID is not an int or an identity, he is the label of an operating system user, and all processes created by that user are the ID.For Linux systems, when a user logs in, a file is created, and the user ID of that file is the ID of the user. All processes created by
