Shell Programming and Scripting

Hi ,

I am new to shell scripting.

I am using Linux for doing scripting.

Below is my script, which takes 2 parameters as input.

test.sh has the below:

Code:

#!/bin/bash
. $HOME/.profile
gpg --yes --no-use-agent -r "$(eval echo \$$2_Var)" -e $1

1st parameter is command line string
2nd parameter is the name of the global variable initialised in .profile file.

if i execute this script using ". ./test.sh global filename" its running prefectly.
But when i try to execute as "sh test.sh global filename" its not executing and output is not created.

Code:

>echo $SHELL
/bin/bash

Can anyone help me on this. I need to run this script using "sh".

Thanks
Sesha

Please use [code] and [/code] tags when posting code, data or logs etc. to preserve formatting and enhance readability, thanks.

if you just type sh
do you end up in the shell?
or do you need to use bash?

Code:

root@M508 /> sh
#

or

Code:

root@M508 /> bash
#

the root@M508 is just in my screen...
should be different in yours

Default SHELL is bash in my environment.


root->june$sh

root->/home/june/gpg> sh test.sh Inbound.dat Golf
: No such file or directoryme/june/.profile

The output file is not created, but when i try

root->/home/june/gpg> . ./test.sh Inbound.dat Golf
: No such file or directory


Its creating the output file (even though says No such file or directory)


Please help.

thanks

is test.sh in the folder /home/june/gpg ?


try this:

Code:

#!/bin/bash
/$HOME/.profile
gpg --yes --no-use-agent -r "$(eval echo \$$2_Var)" -e $1

and then execute with the command:
./test.sh
when you are in the corrext folder

test.sh is available in /home/june/gpg

root->/home/june/gpg> ./test.sh Inbound.dat Golf
sh: ./test.sh: /bin/bash^M: bad interpreter: No such file or directory


Again failed.

The display corruption in your error messages and the odd ^M suggest that your script file is not a unix format text file and contains carriage-return characters. Chances are that it has been edited with a Microsoft program such as "Notepad".

Please post the output from this command which is designed to make control codes visible. In a normal unix format text file the line terminator will be displayed as "$". Any extraneous carriage return characters will show as "\r".

Code:

sed -n l test.sh

Paste the ouput of this

Code:

which bash
which sh

Code:

#!/bin/bash
. $HOME/.profile
gpg --yes --no-use-agent -r "$(eval echo \$$2_Var)" -e $1
