UNIX for Dummies Questions & Answers

Hi All,
How can we execute a Unix file (shell script), which had given "Execute" permission using
chmod +x file1

If i want to execute that file.
prompt>./file1
Hello

How can i make the file permission or something else. such that i can execute it using
prompt>file1
Hello

Note :
file1 contains :
echo "Hello"

Any comments...

add current directory to the PATH variable. You can do this by modifying .profile/.cshrc and place a . before other other directories in the path.

Well, if you're going to do that, I would recommend that you add the "." at the <b>end</b> of your PATH. You can add something like this to the end of your login script:

Code:

PATH="${PATH}:."

It is a little more secure this way...

One note:
If you are the superuser (root), it is not recommended to add the current directory to your path! You might end up running something you didn't mean to run.

can somebody explain me the meaning of placing a "." at the end of a path as mentioned above.

A . means the current directory .... normally the directory you are in at the time when you are in a shell.

thanks Neo. I was confused with the adamant usage of "./" which i generally use for stating the current directory. thanks again

Thanks for all,
Its working fine.
