i want to modify the "cd" change directory command

[Catarino]

hi all
in my work i use ssh to connect to my servers
and i having a "problem" with the "cd" command
example
im in the /var/www/htdocs
and if i want to go to /var/www
i do "cd .."
ok
but in others linux distros i just do .. instead of cd ..
in fedora i get this message
# ..
bash: ..: command not found...
Similar commands are::
'..'
'.'

is there a way to change this?

You should be able to make a bash alias:

 [duke@Rock ~]$ alias ..='cd ..'

Do some research to find out how to make it persistent.

Aliases belong in ~/.bashrc. And if you're running F17, here are a few more useful aliases:

$ cat .bashrc
# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi

# User specific aliases and functions
alias ..='cd ..'
alias lld='ls -dl'
alias cdm='cd /run/media/gene/'
alias lsm='ls /run/media/gene'
alias llm='ls -l /run/media/gene'

Replace gene with your user name. F17 moved the media directory from / to /run/media/$USER.

Actually, the /media directory didn't get moved in F17.

What got changed is how Gnome automounts removable drives. That is what got changed in F17, and they are now mounted at /run/media/<username>

If you want the old mount behaviour, use XFCE, LXDE or KDE.

Isn't that because they all still use udisks? I'm pretty sure that's the case for KDE, and I know that Gnome uses udisks2. I'm guessing that everybody will move to udisks2, eventually.

You get udisk2 installed as well with lxde f17.
And thats when starting from a minimal installation.

Even in Gnome, you can change where it automounts a disk.

Open disk utility, click on the drive, then under the window where it shows the partitions, there is a little gears icon. Click on it, and select "Edit Mount Options" the change the mount point.

You are using a different shell or aliases/shell functions there.

First I would urge you to NOT become dependent on aliases and functions for short everyday commands. Many years ago I built a really extensive set of commands for some ancient VAPL environmnet or similar - and although it was very clean and convenient - I later found that I forgot how to use the basic commands well which made it very difficult to do anything without the magic bag of tricks.

So consider tricks like these ...

alias ..='cd ..'

and particularly these

colorls.sh: alias ll='ls -l' 2>/dev/null
colorls.sh: alias l.='ls -d .*' 2>/dev/null
alias which 'alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'

to be harmful.

aliases like ....

alias cp='cp -i'
alias mv='mv -i'
alias rm='rm -i'

that merely change default options (to prevent accidents) are useful.

Aliases that reduce tedious typing are fine, so I have no problem with ...

alias cdm='cd /run/media/gene/'
alias lsm='ls /run/media/gene'
alias llm='ls -l /run/media/gene'

in principle, but it would be a lot better to just name the directory with a variabe ....

export mymedia="/run/media/$USER"

then use the obvious commands
cd $mymedia
ls $mymedia
ls -ladR $mymedia

There is no advantage and a lot of limitations for aliasas vs shell functions, so
..(){ cd ..;}
instead of
alias ..='cd ..'
