King Abdulaziz University Awk Command in Text Processing Program
Question Description
I’m working on a linux question and need guidance to help me understand better.
Q1- Using the awk utility, filter out the following output to solely show the size and mount point. Show all of your commands in a snapshot.
-bash-4.2$ df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/wd0a 1008M 130M 828M 14% /
/dev/wd0d 1008M 8.6M 949M 1% /suid
/dev/wd0e 63.0G 29.8G 30.1G 50% /usr
/dev/wd0f 19.7G 16.0G 2.7G 85% /var
/dev/wd0g 3.9G 500K 3.7G 0% /tmp
Q2 Modify the script below using the following instructions. Show all of your commands and output in a snapshot.
a) Adjust the thresholds to get some results. Hint: lower the value of 99, 95, 90, etc. For example, the Docker login has 25% capacity of some directories.
b) Instead of the e-mail (like jdoe@comcast.net), echo a message into a file.
# Platform: Not Platform Dependent
#
space= df -k | awk ‘{print $5}’ | tr -d ‘%’
if [ ${space} -gt 99 ]
then mailx -s “Warning” jdoe@comcast.net
Disk space has reached 99%
elif [ ${space} -gt 95} ]
then mailx -s “Warning” jdoe@comcast.net
Disk space has reached 95%
elif [ ${space} -gt 90 ]
then mailx -s “Warning” jdoe@comcast.net
Disk space has reached 90%
else
echo “disk fine”
fi
Q3
You have a UNIX file named “food” with the following information. Show all of your commands and output in a snapshot.
cat food
The menu contains pork.
Using the sed command, change the pork to fish.
