script trick

Tore_1 — Thu, 06 Mar 2003 14:17:58 GMT

Hi, I would like to make an alias or script called subdir, which works like :

cd $(find . -type d -name $1 | head -1)

where $1 is the argument representing the directory.

How am I able to communicate this result from the script, or is there another way to get the same effect?

Hi

A script will not work because it will fork. change directory and then exit back to your local environment without the fork.

Why the script anyway

cd dir is easier.

cd name where name doesnt exist easy error message

A subdir of a directory with the name you want can also comeout . the following is easier in format.

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

Then use the script as . script dir

to avoid the fork

An alias will not work because you cannot setup a parameter to pass easily.

I know this.

subdir should be more than one level down.

Hi,

A workaround is to define it as a function in your .profile.

subdir()
{
if [ $# != 1 ]
then
echo "usage $0: subdirectory"
break
else
cd $(find . -type d -name $1 | head -1)
fi
}

Hi Tore,

one way would be to put the following in a script...

alias changedir="cd `find . -type d -name $1|head -1`"

...run the script by typing...

. ./scriptname

...then enter "changedir" to change directory.
