When I run `conda`, I get `conda: command not found`. Then I realized that the `export` command does not work, and I cannot add the `miniconda3/bin` directory to PATH. ``` $ export PATH="/home/archisman/miniconda3/bin:$PATH" export: Command not found. ``` I don't have `sudo` access. When I run `echo $0` it says: csh. Is there any way to fix this issue? I want to add the directory containing `conda` to PATH so that I can use `conda` without going to that directory. - [centos](https://unix.stackexchange.com/questions/tagged/centos "show questions tagged 'centos'") - [path](https://unix.stackexchange.com/questions/tagged/path "show questions tagged 'path'") [Share](https://unix.stackexchange.com/q/680370 "Short permalink to this question") [Improve this question](https://unix.stackexchange.com/posts/680370/edit) Follow [edited Dec 6, 2021 at 14:50](https://unix.stackexchange.com/posts/680370/revisions "show all edits to this post") [](https://unix.stackexchange.com/users/117549/jeff-schaller) [Jeff Schaller](https://unix.stackexchange.com/users/117549/jeff-schaller)♦ 69k3535 gold badges122122 silver badges268268 bronze badges asked Dec 6, 2021 at 13:14 [](https://unix.stackexchange.com/users/55205/archisman-panigrahi) [Archisman Panigrahi](https://unix.stackexchange.com/users/55205/archisman-panigrahi) 67322 gold badges77 silver badges2121 bronze badges 0 [Add a comment](https://unix.stackexchange.com/questions/680370/how-to-fix-export-command-not-found-in-centos "Use comments to ask for more information or suggest improvements.

So if `export` is not found, you are in a different type of shell. In your case, `echo $0` indicates that your shell is `csh`, where the equivalent syntax would be ``` setenv PATH "/home/archisman/miniconda3/bin:$PATH" ``` However if you are unfamiliar with `csh`, you will almost certainly find it easier to switch to a more familiar shell such as `bash` or `zsh`. If `csh` has been set as your *login shell* by a system administrator, then you can likely change that in CentOS *without* `sudo` privileges using the `chsh` command: ``` chsh -s /bin/bash ``` If changing your own login shell in this way is not permitted (because `chsh` is not setuid root on your system, or `/bin/bash` is not listed in `/etc/shells` for example), then the "old school" workaround is to create (or edit, if it already exists) a `~/.login` file and `exec bash` (or `exec zsh`) from there to immediately replace the login shell each time you start one.
