Bash script to fill in a template
I have looked for this elsewhere but not able to find something that matches my requirements.
The template below is the one I need to use :
dn: uid=$1,ou=home,dc=chan,dc=com
objectClass: organizationalPerson
objectClass: person
objectClass: inetOrgPerson
objectClass: top
cn: $2
sn: $3
userid: $1
userPassword:
I need to script in such a way that populates the following fields $1,$2,$3,$4 with the input that I give it and then outputs to a new file thus allowing to run it using the blank template.
bash shell-script variable

I suspect you are looking for something quite simple like a file my_script that contains:
cat <<<XXX
dn: uid=$1,ou=home,dc=chan,dc=com
objectClass: organizationalPerson
objectClass: person
objectClass: inetOrgPerson
objectClass: top
cn: $2
sn: $3
userid: $1
userPassword:
XXX
To use the above, simply run:
sh my_script fred 100 200
which will output to stdout (and can be redirected to a file).

Does there actually need to be a template file?
#!/bin/bash
echo "dn: uid=$1,ou=home,dc=chan,dc=com" > $4
echo "objectClass: organizationalPerson" >> $4
echo "objectClass: person" >> $4
echo "objectClass: inetOrgPerson" >> $4
echo "objectClass: top" >> $4
echo "cn: $2" >> $4
echo "sn: $3" >> $4
echo "userid: $1" >> $4
echo "userPassword:" >> $4
You would run ./SCRIPTNAME Value1 Value2 Value3 OutputFileName
otherwise
You script would be:
#!/bin/bash
var1=$1
var2=$2
var3=$3
file=$4
cat TemplateFile > $file
sed -i "s/1/$var1/g" $file
sed -i "s/2/$var2/g" $file
sed -i "s/3/$var3/g" $file
and your template file would be
dn: uid=1,ou=home,dc=chan,dc=com
objectClass: organizationalPerson
objectClass: person
objectClass: inetOrgPerson
objectClass: top
cn: 2
sn: 3
userid: 1

Don't use repeated redirections. Rather than slapping ">> $4" on the end of each line, just doexec > $4at the start.

Use perl to replace variables with their values:
export world=World beautiful=wonderful
echo 'I love you, $world! You are $beautiful.' >my_template.txt
perl -pe 's|$([A-Za-z_]+)|$ENV{$1}|g' my_template.txt
The output: I love you, World! You are wonderful.
my_template.txt can contain variables prefixed with $.
