# Login to server

For this workshop, please log into your account\@ALPS1 server. You can use any SSH client, such as [Putty](http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html). For file transfer between the ALPS1 server and your PC/laptop, you can use any SFTP client such as [WinSCP](https://winscp.net/eng/download.php).

## Change `dircolor`

When you log into ALPS1, the default colors are too dark.

We will change the this behavior by editing `.bashrc` using `vi`.

`vi .bashrc`

Go to the bottom of the file, click `i` to start editing the file. Copy below command and paste into `.bashrc`.

```
export LS_OPTIONS='--color=auto'

LS_COLORS='no=00:fi=00:di=01;94:ln=01;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:su=37;41:sg=30;43:tw=30;42:ow=34;42:st=37;44:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arj=01;31:*.taz=01;31:*.lzh=01;31:*.zip=01;31:*.z=01;31:*.Z=01;31:*.gz=01;31:*.bz2=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.jpg=01;35:*.jpeg=01;35:*.gif=01;35:*.bmp=01;35:*.pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.png=01;35:*.mov=01;35:*.mpg=01;35:*.mpeg=01;35:*.avi=01;35:*.fli=01;35:*.gl=01;35:*.dl=01;35:*.xcf=01;35:*.xwd=01;35:*.flac=01;35:*.mp3=01;35:*.mpc=01;35:*.ogg=01;35:*.wav=01;35:'

export LS_COLORS
```

Then save the file by click `Esc` and `shift zz` the shortcut command to save and close the file. Then use `. .bashrc` to apply the new setting. Next time when you login, the `dircolor` will change automatically.

## Change vim color

Besides `dircolor`, the default color scheme of the vim editor is also too dark.

![Default vim](/files/-M44VwEcTXK1Dz3A14sj)

To change this, we create a file called `.vimrc`

`vi ~/.vimrc`

And add `colorscheme desert` to the file. Then save the file by click `Esc` and `shift zz` to save and close the file.

We open `.bashrc` again, and we now use the new color scheme. To close the file without saving, click `Esc` and type `:q` to close file.
