[SOLVED] cd && ls

atjurhs · 12-20-2016, 01:35 PM

hi guys,

on a previous linux system i was able to write this little "alias/script"

Code:

alias ll='ls -alhF'
change_dir_and_list
 {
 cd "$1" && ll
 }
alias cd='change_dir_and_list'

and it worked perfectly, now the little "alias/script" doesn't work. if i remember right before i was running redhat enterprise 7. now my linux box is running centOS linux 6.7

can somebody tell me what i missed or if there's another way to do this?

my goal is so that everytime i cd a listing of all the files in that directory is shown

thanks!

Todd

What exactly doesn't work? I had to change the first line as ll is already defined on my F25 system

Quote:

[tim@comedian ~]$ cat elias
alias lll='ls -alhF'
change_dir_and_list
{
cd "$1" && lll
}
alias cd='change_dir_and_list'
[tim@comedian ~]$ ./elias Downloads/
./elias: line 2: change_dir_and_list: command not found
./elias: line 4: lll: command not found

it comes back saying

Code:

change_dir_and_list: command not found

If I may offer:

Code:

alias cd="cd $1 && ls -alhF"

How are you using this "alias/script?"

If you are using it as a script, why are you even using an alias in it? That alias goes out of scope when the script completes.

If you want to use the alias or included function from the shell prompt, you must put in a startup file or at the least source it before trying to use it, or the shell will not no about it.

Before use, or add it somewhere to your shell's startup files:

Code:

source aliasfile

or

Code:

. aliasfile

The period is a synonym for the source builtin. I prefer using the more verbose source as it's obvious (I hate going through my distro's stock startup files to find stuff, as searching for a period is a PITA).

I believe the change_dir_and_list must have a "(){" immediately following the command, as in

Code:

change_dir_and_list(){
 cd "$1" && ll
}
alias cd='change_dir_and_list'

jpollard, you are correct the alias does required the () to run, i forgot to include that

many thanks!
