Search a template file and replace with input

Linux and Unix-Like Linux
1

Hi I have a CommonTemplateStop.template file . Inside the file i need to replace the variables DepName and CompInsName with the values(Trade and TradeIns) specified in the script. I have written the below .sh script in linux server which will read the .template file and has to replace the 2 parameters DepName and CompInsName with the values specified in the script .When i call the script below i get the below error:

sed: -e expression #1, char 9: missing command
sed: -e expression #1, char 13: missing command

Am quite a novice in unix scripting. Any help is appreciated.

#!/bin/bash
DepName=Trade
CompInsName=TradeIns
templatefile=/tmp/sam/CommonTemplateStop.template
cat $templatefile|sed -e "/DepName/"
cat $templatefile|sed -e "/CompInsName/"

Template file given below :

<?xml version="1.0" encoding="UTF-8" ?>

where is the $ for the variable? e.g.

 /$DepName/

The error msgs are correct - there's no sed command, just addresses. Try

sed "s/CompInsName/$CompInsName/;s/DepName/$DepName/g" file

but make sure the variables don't have "/" in them.

Examples of commands that sed complains about, would be:

sed -n "/DepName/p" "$templatefile"
sed  "/DepName/!d" "$templatefile"

Hi I got the desired output file. Thanks ALL :slight_smile:

#!/bin/bash
CompInsName=$1
DepName=$2
templatefile=/usr/tmp/CommonTemplateStop.template
sed "s/CompInsName/$CompInsName/;s/DepName/$DepName/g" $templatefile > /usr/tmp/autoconfig/CommonTemplateStop.hrb
chmod 774 /usr/tmp/autoconfig/CommonTemplateStop.hrb

Are you sure you need the 774 permission on that file?

Well Rudi i gave that permission just to make sure that the final file is readable and executable. This file shall be invoked by a monitoring application called TIBCO Hawk and the rules implemented.

Do you suggest otherwise?

Does it really need to be executable? Being a config file, I'd guess it needed read permission (and mayhap write for the owner).

Thanks All. Its resolved :slight_smile:
