How to set up and use aliases in Linux shell commands – Guide
An alias is a shortened name for a command or a set of commands. Aliases are commonly placed in startup files, such as ~/.bashrc or ~/.tcshrc, so that they are available to subshells.
alias [name]=‘command’ For example, to alias ls to list all files in the current directory, you could use: alias ls=‘ls -l’ ..
tcsh -V This prints the version of tcsh on the command line.
In bash, the equal sign is used to compare two values. If one value is equal to the other, it is considered a “equal” value. If one value has spaces or tabs, it must be enclosed in quotation marks. Unlike aliases in tcsh, a bash alias does not accept a command-line argument as an input. To create an alias, use the following command: alias -a my_alias This will create an alias for my_alias that takes an argument of “my_value”.
alias a=‘b’ alias b=‘c’ alias c=’d’ This will result in an alias called “a”, “b”, and “c” which each refer to the previous alias. To avoid this, use the following syntax: alias a=‘b’ alias b=‘c’ alias c=’d’ ..
