A script worked improperly

[chrisych]

I entered the following commands one by one and worked very fine in RedHat.

service squid stop
rpm -e squid
rpm -ivh /root/squid-2.4.STABLE6-1.7.2.i386.rpm
cd /etc/squid
cp squid.conf.rpmsave squid.conf
service squid start

When I saved them as a script, it didn't work properly.
(add #!/bin/sh and chmod 755)

Can anyone tell me how to solve this problem?

Thank you very much!

Need more information.

What command did you use to run the script.
What was the error message.
Post the script

rpm -ivh /root/squid-2.4.STABLE6-1.7.2.i386.rpm
cd /etc/squid
cp squid.conf.rpmsave squid.conf
service squid start

into a file called "reborn" and chmod it to 755.

I thought that as I typed "reborn" and the system showed me "command not found".

But I typed "./reborn" and it worked pretty good.

I am a Linux beginner.

Actually, I don't know the difference between "bash" and "sh".

Thanks for your helps.

Forgetting the './' in front of the script is a common mistake by beginners. The './' means to look for the script in the current directory. If you forget the './' Linux looks for the script in the directories listed in the PATH variable. You can see that with:

echo $PATH

In Linux "bash" and "sh" are the same thing. /bin/sh is what's called a symbolic link that points to /bin/bash.
