Bash script accepting variables in valid number format
Hi Experts
I would like to ask if there is a way to validate if the variable passed is in this kind of sample format "06-10" or "10-01". It was really a challenge to me on how to start and echnically the "6-10" stands for "June 10" and "10-01" stands as "October 1", overall it needs to have like of a "Month-Day" valid in number format. I would like to have an if-then statement that would validate if the variables passed are in correct, something like these:
I would like to change the format of an integer type number adding zeros to the left of it in a script in bash. For example
number=1
echo $number
00001

Hello.
I can use any particular (stupid or not) format when using bash date command.
Example :
~> date --date "now" '+%Y-%m-%d %H!%M!%S'

escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
