Hello,
I am attaching a code snippet. Some of the variables are set in earlier code like count, arrays harr1, harr2, barr1 and barr2. The code below gives syntax errors. I am very new to Bash.
Code:
for (( i=0; i<=$(( $count -1 )); i++ ))
do
#Now read the element at barr2 location i. Also find element at barr1 at position i. Now find the position of this element in harr1. The second value we will get by reading harr2 at this position.
first=$barr2[$i]
search = $barr1[$i]
for (( j=0; j<=5000; j++ ))
do
if [ harr1[$j] -eq $search ]; then
break;
fi
done
second = $harr2[$j]
echo $second
done
The error generated is in the if statement. The error says:
unary operator expected

English(3pm) Perl Programmers Reference Guide English(3pm)NAME
English - use nice English (or awk) names for ugly punctuation variables
SYNOPSIS
use English;
use English qw( -no_match_vars ) ; # Avoids regex performance penalty
# in perl 5.16 and earlier
...
if ($ERRNO =~ /denied/) { ... }
DESCRIPTION
This module provides aliases for the built-in variables whose names no one seems to like to read. Variables with side-effects which get
triggered just by accessing them (like $0) will still be affected.
For those variables that have an awk version, both long and short English alternatives are provided. For example, the $/ variable can be
referred to either $RS or $INPUT_RECORD_SEPARATOR if you are using the English module.
See perlvar for a complete list of these.
PERFORMANCE
NOTE: This was fixed in perl 5.20. Mentioning these three variables no longer makes a speed difference. This section still applies if
your code is to run on perl 5.18 or earlier.
This module can provoke sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters
in your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH, try doing
use English qw( -no_match_vars ) ;
. It is especially important to do this in modules to avoid penalizing all applications which use them.
