-a and -z work inside the test command. -a is logical AND.
Here you need &&, the shell's logical AND.
Do not use `command in backticks`! It runs the command output in a subshell!
No harm *here* because grep -q suppresses the output. But generally confusing and risky.
Last but not least, it is recommended to "quote" variables in command arguments.
Not required *here* because you set them to sane values.
do odd things if UNINUM has a * or a space character.
are safe.
Your comments raised few doubts in my code, can you please guide me here
1) I am always using the flower brackets for all variables in my shell script like ${VAR}, is that a wrong approach? one issue i just learned is without double quotes the newlines are lost to word split, are there any other drawbacks before i go ahead and replace everywhere in my scripts?
2) I have the following piece code which i am executing via shell script, i am not suppose to use the backticks since it opens up and executes the code in a new sub shell? this works fine for me and serves the purpose
Can somebody please guide me towards right syntax:
#!/bin/ksh
if i = $(grep $NAME filename)
echo "Name Found"
else
echo " Name not Found"
fi

ppi::statement::data
PPI::Statement::Data(3) User Contributed Perl Documentation PPI::Statement::Data(3)NAME
PPI::Statement::Data - The __DATA__ section of a file
SYNOPSIS
# Normal content
__DATA__
This: data
is: part
of: the
PPI::Statement::Data: object
INHERITANCE
PPI::Statement::Compound
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
"PPI::Statement::Data" is a utility class designed to hold content in the __DATA__ section of a file. It provides a single statement to
hold all of the data.
METHODS
"PPI::Statement::Data" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.
However, it is expected to gain methods for accessing the data directly, (as a filehandle for example) just as you would access the data in
the Perl code itself.
TO DO
- Add the methods to read in the data
- Add some proper unit testing
SUPPORT
See the support section in the main module.
