Trying to do some control flow parsing based on the index postion of an array member. Here is the pseudo code I am trying to write in (preferably in pure bash) where possible. I am thinking regex with do the trick, but need a little help.
pesudo code
if [[ array[3] == ENDSINFIVEINTS ]]; then
do stuff
fi
Thanks in advance.

I found this regex...
but not sure how to incorporate it
^\d{5}$
#! /bin/bash
x=( 3214 4567 12345 2134 )
echo ${x[2]} | grep -q -E "^[0-9]{5}$"
if [ $? -eq 0 ]
then
<do_stuff>
fi
grep -E [0-9]{5}$
This checks for the last five characters having digits. Note that this will return true if the last 5 or more characters are digits as well.
case ${array[3]} in *[0-9][0-9][0-9][0-9][0-9]) echo OK;; esac
If you really want to use bash's regex matching, to handle differences in bash versions you'd want to use a variable to hold the regex.
#!/bin/bash
re='[[:digit:]]{5}$'
a=(0 1 2 12345 1234)
if [[ ${a[3]} =~ $re ]]; then
echo true
fi
