xombboxer · 04-30-2011, 05:13 AM

i have a script where i need to pass an argument "1234:-)"

if i run this as

./shell.sh 1234:-)

it wont work because invalid character.

i need to handle this with expect utility so if i pass it as

./shell.sh "1234:-\)"

no issue in bash but expect does not recognize this.

how to handle this

What about single quotes?

Code:

./shell.sh '1234:-)'

:-)

Expect works fine, without escaping:

Code:

$ ./shell.tcl "1234:-)"
1234:-)

$ cat shell.tcl 

#!/usr/bin/expect -f
puts "[lindex $argv 0]"

I'm trying single quotes ..

it seems both single and double quotes are same.

if i pass

./shell.sh '1234:-\)'

from bash i dont get any error.
when it goes to expect it will be 1234:-). this is what i expect, but still im getting message "incorrect password"

Please, try double or single quotes without the escaped parenthesis (as shown in the examples above):

Code:

./shell.sh "1234:-)"

or

Code:

./shell.sh '1234:-)'

Or maybe if passing through a bash script to the expect script you need quotes within quotes to keep it all together:

Code:

./shell.sh "'1234:-)'"

Within single quotes, nothing is substituted, and backslashes are interpreted literally.

Within double quotes, some things still are substituted.

To learn more about BASH scripting, see the "LinuxCommand" tutorial (there's a link in my sig).
