What is the difference between ~ . profile and ~ . bash_profile? The original sh sourced profile on startup bash will try to source bash_profile first, but if that doesn't exist, it will source profile Note that if bash is started as sh (e g bin sh is a link to bin bash) or is started with the --posix flag, it tries to emulate sh, and only reads profile Footnotes: Actually, the first one of bash_profile, bash_login, profile See also: Bash
When exactly do the scripts in etc profile. d get executed? In etc profile d I got a script called logchk sh which is meant to send an email to the admin email address via bin mail If someone logs in via ssh user@serveradress this script is properly executed and the email is sent However, it depends on the login method if the script is executed or not What works is the following
What is the difference between ~ . profile, ~ . bashrc, ~ . bash_profile . . . The one possible exception is etc profile and profile, which may be used by multiple different shells (including at least sh and bash) There is something called an environment associated with every running process which can contain variables that may affect the behavior of said process
profile - Find out what scripts are being run by bash at login - Unix . . . My terminal starts a login shell, so ~ bash_profile is sourced, followed by ~ profile and ~ bashrc Only in ~ profile do I create the paths entries which are duplicated To be pedantic, this is the order in which the files that SHOULD be sourced are being sourced: Sourced etc profile Sourced etc bash bashrc Sourced bash_profile Sourced
How to correctly add a path to PATH? - Unix Linux Stack Exchange The profile file is read by login shells, so it will only take effect the next time you log in (Some systems configure terminals to read a login shell; in that case you can start a new terminal window, but the setting will take effect only for programs started via a terminal, and how to set PATH for all programs depends on the system )
What is the purpose of . bashrc and how does it work? My comment is just a stronger statement of Ilmari Karonen's 2014 comment It is factually incorrect to say " bashrc runs on every interactive shell launch" A login shell is an interactive shell, and it's the counterexample: a login shell does not run bashrc It would be correct to say " bashrc is run by every interactive non-login shell" Bash Reference Manual, section 6 2, "Bash Startup FIles"
