Just a quick script to reverse some input, using Bash and the FOSS "rev" program. It's amazing how easy it is to manipulate things with Bash. I love it!
Bash script version:
One-liner version:
Or how about this more ridiculous example (one that doesn't use the "rev" program):
Ridiculous one-liner version (one that doesn't use the 'rev' program):
Bash script version:
#!/bin/bash
#Simple script to reverse an input name
echo "Enter your name";read 'myname'
echo "Your name spelled backwards is: $( echo $myname | rev )"
exit 0
One-liner version:
echo -n "what is your name?";read name;echo "$name" |rev

numChars=$(echo -n "$myname" |wc -c)
revname=
while [ $numChars -gt 0 ]

numChars=$(expr $numChars - 1)
done
