how to get a-z command list manual of ubuntu
I know of two places to find lists of keyboard commands. Neither is complete, but between both of them, I think you'll find them useful.
-
Open Welcome and click on Getting Started. There is a button there for Keyboard Shortcuts.
-
Open the Ubuntu MATE Guide either from the main Ubuntu MATE menu or from here on the website: Ubuntu MATE Guide Online. There is a section at the end listing even more keyboard shortcuts.
Below is the command to get fullest possible list of commands which are declared in $PATH
variable:
find $(echo $PATH | sed 's/:/\n/g' | sort -u) -type f -executable -follow -exec basename {} \; | sort -u
How it works:
-
echo $PATH | sed 's/:/\n/g' | sort -u
print$PATH
variable and then use new line as delimeter, sorts unique values -
find ...
finds executables and print their filenames -
sort -u
finally prints list of unique commands
On Ubuntu MATE system I get the following amounts of commands:
- fresh 20.04 LTS VM returns 2019
- fresh 21.04 VM returns 2051
You can read more about each command by:
- using their builtin help by executing with
-h
or--help
command-line argument; - using manual pages
man commandname
(in terminal) oryelp man:commandname
(in GUI) - using online manual pages at http://manpages.ubuntu.com/
