Shell Programming and Scripting

Hi,

I'm trying to create a little script:

if [ -d $1 ]
then
cd $1
ls -l $1
fi

so I can make a new command: cl that does both.

simple enough but I noticed that after executing I'm returned to my original location. How do I surpress that behaviour? I'm using bash-2 on HP-UX 11.

Thanks.

That's because it's executed in a subshell.

You could add a function to .bashrc something like

Code:

cl()
{
   if [ -d "$1" ]; then
      cd "$1"
      ls -l
   fi
}

Cheers

Have a question here ....
See the following 2 aliases ....

alias cl="cd scripts ; ls -lrt"
alias cla="cd $1 ; ls -lrt"

Here is the concern ...
1)After running the first alias command 'cl' , the current directory is $HOME/scripts
2) After running the second alias command 'cla scripts' , the current directory is $HOME only.

For both alias commands , o/p is nothing but list of "scripts" directory.

Any ideas what's happening here .... ?

That is the ksh syntax for an alias. But an alias in ksh cannot have parameters. That $1 will not be the parameter on the alias invocation. Use a function if you want parameters.

. ./yourscript.sh

a bit late maybe but I thought I might post the result:

cl()
{
if [ -d $1 ]
then
cd $1
ls -la
else
cd $HOME
ls -la
fi
}

then

./cl.sh

in my .profile works very well on ksh and in bash
