Shell Programming and Scripting

Please, remove the echo. I presume that it was there for testing purposes.

Hi I removed the echo but i am not able to pass the ${node} value from the input file to the current script. Basically my requirement again is to read a input file which has comma seperated values . Now in the script i need to replace those values where i have put ${node}. Below is the input file and the script. i presume a error in my while statement !!

Input File :--

Code:

PSIHUBV1,PSIHUB04

Script :--

Code:

 #! /bin/bash
file=/usr/opt/temp/aorc.prop
tr ',' '\n' < $file | while read node; do 
cfsend n:"${node}" port:46464 uid:PSMFT pwd:Tib3 pn:CHCKDIR ud:5563 trtype:c rcmd:"pwd" >> out.txt
done

With the output from the echo commands you showed us in post #7 in this thread, it appears that the tr and while read loop are behaving as expected. What makes you believe that it is not working correctly?

Note that the script should now work with an input file that contains a list of comma- and/or newline-separated list of hosts. It will not, however, make any attempt to grab only a hostname from an input line like:

Code:

variable=hostname

Are you saying that your script doesn't work if you feed it data from a file in this alternative format?

Note also that if a first line in a shell script starts with a space character followed by #!, that line is NOTHING but a comment; it does not affect what interpreter is used to process that script. #! in a script has absolutely no effect on the running of that script unless those are the 1st two characters in the file. (And, there shouldn't be a space following the #! either.)

Thanks All. It worked.
