Hi,
I would like to create an IF statement where if a variable is equal to at least one of 2 (or more) values then the script proceeds. For example:
TEST_VAR=2
if ; then
echo success!
else
echo failure
fi
I understand that the above syntax is wrong but I feel it must be close. Any... (1 Reply)
#!/usr/bin/perl
$output1 = "/home/log.txt"
$output2 = "/home/grep.txt"
#Statement1 creates an output file called log.txt.
#Statement2 greps a line from log.txt and store the result in grep.txt
I want to create a condition where if the file grep.txt is empty repeat process.
Thanks. (1 Reply)

ppi::statement::compound
PPI::Statement::Compound(3) User Contributed Perl Documentation PPI::Statement::Compound(3)NAME
PPI::Statement::Compound - Describes all compound statements
SYNOPSIS
# A compound if statement
if ( foo ) {
bar();
} else {
baz();
}
# A compound loop statement
foreach ( @list ) {
bar($_);
}
INHERITANCE
PPI::Statement::Compound
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
"PPI::Statement::Compound" objects are used to describe all current forms of compound statements, as described in perlsyn.
This covers blocks using "if", "unless", "for", "foreach", "while", and "continue". Please note this does not cover "simple" statements
with trailing conditions. Please note also that "do" is also not part of a compound statement.
# This is NOT a compound statement
my $foo = 1 if $condition;
# This is also not a compound statement
do { ... } until $condition;
METHODS
"PPI::Statement::Compound" has a number of methods in addition to the standard PPI::Statement, PPI::Node and PPI::Element methods.
type
The "type" method returns the syntactic type of the compound statement.
There are four basic compound statement types.
The 'if' type includes all variations of the if and unless statements, including any 'elsif' or 'else' parts of the compound statement.
The 'while' type describes the standard while and until statements, but again does not describes simple statements with a trailing while.
The 'for' type covers the C-style for loops, regardless of whether they were declared using 'for' or 'foreach'.
The 'foreach' type covers loops that iterate over collections, regardless of whether they were declared using 'for' or 'foreach'.
All of the compounds are a variation on one of these four.
Returns the simple string 'if', 'for', 'foreach' or 'while', or "undef" if the type cannot be determined.
