check if a given directory exits. 1

[caesarkim]

does anybody know a good tutorial about shell scripting?

I just started learning a shell script.

I just want to know how to check if a given directory exists and how to write to a plain text file.

Thanks.

first make sure your index file is up to date:

updatedb

Then "locate directory"

Use pico to create a text file. Or you could use nano:

pico myfile.txt or nano myfile.txt

Write to it, then press CTRL+X (Save it!)

Find out if directiry exist:

if [ -d /My/directory/psth ]
then
echo "Exists"
else
echo "Doesn't exist"
fi

To write to file:

1) Use redirection:

echo "First line" >MyFile

2) Use and editor: ed, ex vi, emacs, pico, etc...

3) Read the tutorials.

My favouries are the O'Reiley series. This is a shamesless plug, and I don't work for them. IN particular you might want to look at this Unix site which I still refer to from time to time.
