Custom Shell Prompt

Linux da Shell prompt da ne yazacağını PS1 değişkeni belirler.

# echo $PS1

Linux distrolarına göre farklı değerler alırsınız.

Örnekler:

\\u@\h \\W]\\$

${debian_chroot:+($debian_chroot)}\u@\h:\w\$

Bunu dilediğiniz gibi değiştirebilirsiniz.

# vi /etc/bashrc

bashrc dosyasının sonuna PS1 için yeni değer atayabilirsiniz.

Örnek:

export PS1=’BATUR / ${debian_chroot:+($debian_chroot)}\u@\h:\w\$’

export PS1=BATUR/$PS1

export PS1=’touch me : ‘
