I know that to list all aliases in a given bash session with
alias -p. Is there a way to get a list of all the temporary aliases in a given bash session, i.e. all aliases that aren't in my bash profile?
It's not that simple. There is no concept of "temporary" aliases in bash, and for bash any command executed by sourcing .bashrc is the same as any you type into the command line. Moreover the bash profile files could define some aliases only under some circumstances.
You could save into a variable (or file) the aliases which are set after the bash profile files are executed and then, when you need it, check the difference between such variable and the aliases currently set:
You could do this with the following:
This works by comparing the current list of aliases with the aliases present in a brand new shell.
