===== Length Operator =====
There are two way to get length of the string.
The simplest one is ${#varname}, which returns the length o... # 3
# 'c' (in #3 position) matches before '1'.</code>
This is the near equivalent of strchr... e command-line arguments, when no such arguments are given. This is shown in the following script:

omparisons ===
<code>
#!/bin/bash
a=4
b=5
# Here "a" and "b" can be treated either as integers or strings.
# There is some blurring between the arithmetic and string comparisons,
#+ since Bash variables are not strongly typed.
# Bash permits integer oper... g result!
exit 0

=== Example 7-7. zmore ===
<code>
#!/bin/bash
# zmore
# View gzipped f
