Hi. Could you please help to explain what is the meaning of [-f ~/.bashrc] in the bashprofile setup below? Thanks
# if [ -f ~/.bashrc ]; then source ~/.bashrc fi
The “[ -f ~/.bashrc]” is known as a test command in bash. This command, which includes the “-f” expression, will check if the ~/.bashrc file exists (i.e. the file .bashrc is in your home directory) and is a regular file (i.e. is not a directory).
If the expression [ -f ~/.bashrc] is true, then the program will run the “source ~/.bashrc” command.
