![]() ![]() If your PATH is broken, consider running /alt/bin/shellreset to replace your startup files by the Maths defaults. If not, you may find that you are missing some local commands or running an outdated version of LaTeX. The default PATH is given by this line in our central Bashrc file:Įxport PATH="$/bin:/alt/bin:/usr/local/bin:/bin:/usr/bin."įor your shell to work properly, your PATH must contain the directoriesĪnd /alt/bin must come before the others. PATH is the list of directories in which the shell searches for the commands you type. bashrc calls it, take care not to set the same environment variable differently in both files. Note: Historically DAMTP users have set environment variables in their. The environment variables which you are most likely to need to change are PATH, PRINTER, VISUAL/EDITOR and PS1. If this happens, terminate that session and start a new shell without your changes. Note: modifying environment variables incorrectly can confuse your shell. echo $HOME will tell you where your home directory is. You can see a complete list of them by typing set, or check the value of one variable with the echo command e.g. The bash shell has many environment variables (with names in CAPITALS) which affect its behaviour. Then from any computer you can type the name of the alias - in this case embroil - and you will be put into your data directory there. (replacing user abc99 with your login and embroil with whatever computer you are using for data space). Alternatively consider adding /alt/applic/user-maint/abc99/bin to your PATH - see below.Īn alias to change directory to where your data space is. If you find it difficult to remember that the unix command cp is used to copy files.Īlias programb=/alt/applic/user-maint/abc99/bin/Īn alias to run a program installed in the shared software area. The alias command is used to rename a command to another or create a short alias for a long command. With the default Maths config files this means adding them after the lines Your changes need to be added after any commands to run global configuration files or they may be overwritten. ![]() bashrc to have a lasting effect, not just typed into a terminal window. Remember, all commands mentioned below should be added to your.The reason is that WinSCP runs a non-login shell and gets confused by output from. There is one exception to the above rule: commands producing output should go in. Delete the echo command afterwards - read on to find out why. bashrc and run an ssh session (to ensure you get a login shell). If you want to test whether this happens for you, add an echo command to. Then your shell will behave the same whether it is a login shell or not. bash users can check whether it's a login shell with the command shopt login_shell. ![]()
