linux: how to execute profile file

Question

My colleague gave me a file containing lots of configs such as

alias  ll="ls -l"
alias  lr="ls -lrt"
alias  gv="vim -g"

How can I use(execute) this profile?

Solution 1

You can load the profile using source command:

source <profile-filename>

eg:

source ~/.bash_profile

Solution 2

For your custom aliases, the best place should be at ~/.bash_aliases. You must just be sure the ~/.bashrc file already contains the following lines:

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

or in a more concise manner:

[ -f ~/.bash_aliases ] && . ~/.bash_aliases

To load them immediately, source it. Otherwise, aliases will be loaded at every terminal opening. To check, use the alias command without argument.
