    I can't get this to work. Try this instead /bin/bash -lixc exit 2>&1 | awk 'match($0, /^+* (\.|source) (.+)/, s) {print s[2]}'. I also find that strace does a better job: strace -t -e trace='openat' --decode-fds -e signal=none bash -lic exit 2>&1 | grep -P --no-color 'openat.+(?<!\(No such file or directory\))$' Commented Apr 13, 2021 at 19:30

    @smac89 if you want your strace to work on WSL as well, use the following strace -e trace='openat' -e signal=none bash -lic exit 2>&1 | cut -d\" -f2 | grep -Ev "locale/|langpack|/dev/null|/dev/tty|^*/$|+++ exited|logout|.*so.*" to get the proper list of config files only, without the fancy stuff.

    This is only half of a good idea.  Yes, -x will show all the commands that the shell executes, but the OP is interested in the initialization files that bash runs automatically, and -x does not show these as source or . commands.  A better answer would be to tell the OP to look at the full -x output, figure out what commands are being executed, and then grep everything to find out what files those commands are in. … (Cont’d) Commented Apr 12, 2022 at 5:33

    (Cont’d) … A slightly better approach would be to use -v and see the literal contents of the initialization files — that will show comments, and many system shell script files have header comments giving their names. … … … … … … … … … … … … … … … … … … … … P.S.  You talk about “the source command or the . alias.”  I believe that there is a command that simply has two names.  Can you provide a reference for your claim that . is only an alias for source?
