problem in running a shell script

Francis Ancheta — Fri, 20 Jun 2003 09:54:49 GMT

Hi,

One last question for the day. Why is it when ever I download a .tar.gz file then extract it, I have problems in running the shell script.

I have the following error:

[root@TSHDSFW yahoopops-0.4.5]# pwd
/home/downloads/Yahoopops/yahoopops-0.4.5
[root@TSHDSFW yahoopops-0.4.5]# ls
common docs README src ypcompile ypcompilelinux ypinstalllinux
[root@TSHDSFW yahoopops-0.4.5]# ypcompile
-bash: ypcompile: command not found
[root@TSHDSFW yahoopops-0.4.5]#

attached is the shell script

Hello!

It's because your "." directory not in your
PATH, if you run it you can run by adding "./"
to the name : ./ypcompile

Try
./ypcompile
You have to add ./ when script is not an internal command.

Good night !

Ceasar Thanks ... he he he ... I used to laugh at my students in Microsoft if they had problems like this ... Dose of my own medicine.

one thing I learned in Linux that Microsoft ignores.

"Little things matter in Linux even if its just a dot a slash or a capital letter"

you can add the '.' directory to the PATH variable so:

export PATH=$PATH:.

you can add this line in /etc/bashrc (to execute it for all the users, when they log in) or in
the file .bashrc in the home directories of the users that want it.

hi

that is because your current directory(.) is not in the path.

do an echo $PATH

and u will see that ur current directory is not there.

so do an ./ypcompile.

and dont try adding current directory to your path. it is considered a bad practice.

Same issue for me Balaji ! What do you plan for the w.e. ?

I 100% agree with the path issue, which is bad practice, and dangerous as for security reasons. That's why I didn't suggest it, but it's still possible and technically correct.
A good old ./ seems better anyway.

I never thought about it could be a security risk. And it isn't difficult to figure out why.
nevertheless this, I agree with you: it's a good idea specify explicitely that I want execute the command that resides in the current directory.
