You may want to try the aliases...
Code:
root@bt:~# cat ~/.aliases 
#!/bin/bash
MYCMD()
{
    cmd=$(echo $1 | sed 's/.*@[a-z.]*//g' )
    cd $cmd
}

Code:
root@bt:~# MYCMD fish://mfong@vhl.gov.nd/root/Desktop/study
root@bt:~/Desktop/study#

It works just as a script sourced in the shell with functions and sourcing makes the function call available in the shell...

Normally, .aliases is sourced when you log in. i.e. you should/will find this piece of code . ~/.aliases in your ~/.profile or ~/.bashrc depending on your shell

Hello ahamed. It is about to be done. We are very close. When I type

mycmd fish://jackboy@reacs1.ul.gov.tr/home_put1/jackboy

it gives

-bash: cd: 1.ul.gov.tr/home_put1/jackboy: No such file or directory

it must do

cd /home_put1/jackboy

(however your code does cd 1.ul.gov.tr/home_put1/jackboy)

how can it be fixed ?



thanks

Try this...
Code:
#!/bin/bash
MYCMD()
{
    cmd=$(echo $1 | sed 's/.*@[a-z.0-9]*//g' )
    cd $cmd
}

Let me see if I can generalize it even more!...
