Link doesnt work anymore, can you please repost ??
Here's what i actually need : suppose i want my current ip address to be stored as a variable, then after some time, i store my now-current ip in some other variable, and then i want to compare these two through IF clause (i wonder if IF only compares strings and not numbers) . Is it possible ?
As you may have noticed, I'm new to linux bash, though I know windows batch programming pretty much - so if possible, please be elaborative.
The link above was from the Advanced Bash Scripting Guide. You can find the latest version on The Linux Documentation Project, here. Regarding your specific issue, look at Command Substitution (chapter 11 in the above cited guide).
#file where to store IP
#get external IP
#get old IP
if [ -f "$ipfile" ]; then
if [ "$IP" = "$OLDIP" ]; then
echo "IPs match"
echo "IPs don't match"
#save new IP to the file
echo $IP > $ipfile

Reason: forgot a "then" in if condition
