Shell Programming and Scripting

Hi, i want to start my script only by the name of it.



$ scriptName


normaly i have to use ./scriptName oder sh scriptName

is there a way to do that in bash or sh ?

Hi,

Try this:
1. Type a command called as "pwd" on your terminal(where you have written your program), copy the result.

2. Now type the command "setenv PATH (result of pwd command, excluding the() braces):{$PATH}

This should work.

eg:1. pwd
/home/vishwa/programs

2. setenv PATH /home/vishwa/programs:{$PATH}

well the setenv command is not found but thats not the problem i think,

you want to add the path of the script to the path of the system variables so i can reach the script in any directory, but thats not the problem i have

i have the script in the same directory where i want to open it, i wanted to know if there is a way without changing some system variables to open it by name so i can call it on an other host where i have copyed it too.

is there a way ?

You place it in the /usr/bin folder, I think.

Edit: Ok, not quite.. I think that just allows you to type scriptName.sh in any directory

Edit again: Aha, got it. Add #!/bin/bash to the top of your script file, remove the .sh extension, and then put it in your /usr/bin folder. You will need to use sudo mv to move it, and sudo chmod +x to execute it.

$ scriptName will then execute /usr/bin/scriptName, interpreting the commands with the bash library.

I already did that but
$ scriptName
bash : criptName : command not found

$cat Script

#!/usr/bin/bash

echo "test"


ls -l scriptName

-rwx-r-xr-x


with ./scriptName it works
or sh scriptName

OS : Debian Lenny
Alternativ : cygwin

on both the same "problem"

In OS X:

brian-1000h:~ admin$ sudo nano /etc/bin/test1
Password:

-----Nano-----
#!/bin/bash
echo "omgwtfhax"

Ctrl+x , y, Enter

brian-1000h:~ admin$ sudo chmod +x /usr/bin/test1
brian-1000h:~ admin$ test1
omgwtfhax


Dunno what the difference is there, other than I have #!/bin/bash at the top of mine, and you have #!/usr/bin/bash.. maybe it's not reading the library correctly because of the /usr/ bit. That would explain why you have to tell it that it's a bash file.

The setenv command is a csh thing.

To add a directory to your PATH in bash:
export PATH=${PATH}:/path/to/directory

Add this to your local profile or /etc/profile. You could also copy the script to any directory already defined in your current path:

echo $PATH
