Bash delete file when variable = x
- by twigg
I'm creating a bash script which reboots the system at each reboot it adds a new line to a text file, I then read the text file before each reboot. Once the variable holding the number of lines reaches say 10 I want the script to delete the text file (at which point on the next reboot it will see the file isn't there, brake the loop and promote the user to start again). I tried this:
exec < text.txt
nol=0
while read line
do
nol=`expr $nol + 1`
done
reboot_count=10
if ["$nol" == "$reboot_count"];
then
rm text.txt
fi
but this doesn't seem to be working, all help is appreciated :)
