Please try the below code.
sub create_db_install_val(){
$File_name="DB_INSTALL_VALIDATION.sh";
print "\n Shell name to validate DB Installation Completion is $File
+_name\n";
$MYSCRIPT=<<SCRIPT;
#!/bin/sh
FILE="/scratch/pratranj/DB_11.2.0.1.0/config/setup.log"
STRING="Completed creating database instance"
EXIT=1
while : ;do
[[ -f "\$FILE" ]] && grep -q "\$STRING" "\$FILE" && echo "DB Install
+ation is completed" && break
sleep 5
done
SCRIPT
open (FILE,">$File_name") or die "cannot open $File_name file";
print FILE $MYSCRIPT;
close(FILE);
}
Output:
-------
$ cat DB_INSTALL_VALIDATION.sh
#!/bin/sh
FILE="/scratch/pratranj/DB_11.2.0.1.0/config/setup.log"
STRING="Completed creating database instance"
EXIT=1
while : ;do
[[ -f "$FILE" ]] && grep -q "$STRING" "$FILE" && echo "DB Installati

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
