## Default SHELL
In general, **`/bin/bash` is the recommended default user's SHELL** when working in Merlin.
Some users might notice that BASH is not the default SHELL when login to Merlin systems, or they might need to run a different SHELL.
This is probably because when the PSI account was requested, no SHELL description was specified or a different one was requested explicitly by the requestor.
Users can check which is the default SHELL specified in the PSI account with the following command:
```bash
getent passwd $USER | awk -F: '{print $NF}'
```
If SHELL does not correspond to the one you need to use, you should request a central change for it.
This is because Merlin accounts are central PSI accounts. Hence, **change must be requested via [PSI Service Now](/merlin6/contact.html#psi-service-now)**.
Alternatively, if you work on other PSI Linux systems but for Merlin you need a different SHELL type, a temporary change can be performed during login startup.
You can update one of the following files:
* `~/.login`
* `~/.profile`
* Any `rc` or `profile` file in your home directory (i.e. `.cshrc`, `.bashrc`, `.bash_profile`, etc.)
with the following lines:
```bash
# Replace MY_SHELL with the bash type you need
MY_SHELL=/bin/bash
exec $MY_SHELL -l
```
Notice that available *shells* can be found in the following file:
```bash
cat /etc/shells
```
## OpenGL vs Mesa
Some applications can run with OpenGL support. This is only possible when the node contains a GPU card.
