Q. How do I view command line history? I am using Cent OS Linux system.
A. BASH is the default shell for Linux computers. Bash has history command. It display the history list with line numbers i.e. it lists everything you have entered on the command line. You can recall commands from history so that you can save the time.
Task: View your command Line History
Type the following command:
911 man 7 signal 912 man ps 913 man 7 signal 914 man killall 915 killall -l 916 man killall 917 su - 918 su - lighttpd 919 su - lighttpd 920 cd /tmp/ 921 ncftpget -u [email protected]' lan.server.gite.in
So whenever you type a command, that command is saved is a file called .bash_history. Type following commands to get more info:
$ help history
$ man bash (look for Event Designators for more info).
