linux：如何执行配置文件

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?

Answer 1

You can load the profile using source command:

source <profile-filename>

eg:

source ~/.bash_profile

Answer 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.

Answer 3

You can put it in your local .bashrc (or appropriate shell rc file) file if you want it permanently.

cat fileNameProfile >> ~/.bashrc

And for current session:

source ~/.bashrc

If you want it just now, then:

source fileNameProfile

Answer 4

For one time use, copy paste commands to your terminal:-

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

For everytime use, add it in .bashrc.

echo 'alias  ll="ls -l"' >>  ~/.bashrc
echo 'alias  lr="ls -lrt"' >> ~/.bashrc
echo 'alias  gv="vim -g"' >> ~/.bashrc

and then source ~/.bashrc
