UNIX PRACTICAL

NOTE : ALL THESE PROGRAMS ARE DEVELOPED AND TESTED IN UWIN (unix for windows), FOR UNIX TERMINAL

1. YOU HAVE TO CHANGE == (double equals to) to = (single equals to).

IF ANY OTHER PROBLEM OCCURS PLEASE COMMENT (using account or anonymously), WE WELCOME.

Check the output of the following commands.date, ls, who, cal, ps, wc, cat, uname, pwd, mkdir, rmdir, cd, cp, rm, mv, diff, chmod, grep, sed, head, tail, cut, paste, sort, find.
Write shell script

Accept numbers and perform addition, subtraction, division and multiplication.
Accept the string and checks whether the string is palindrome or not.
Accept number and check the number is even or odd, finds the length of the number, sum of the digits in the number.
Accept strings and replace a string by another string.
Accept filename and displays last modification time if file exists, otherwise display appropriate message.
Fetch the data from a file and display data into another file in reverse order.

Write a script to display the date, time and a welcome message (like Good Morning etc.). The time should be displayed with “a.m.” or “p.m.” and not in 24 hours notation.

HH=`date +%H`
time=`date +"%S %p"`
if [ $HH -ge 12 ];then
HH=`expr $HH % 12`
if [ $HH -lt 5 ];then
msg="GOOD AFTERNOON"
elif [ $HH -ge 5 ] && [ $HH -lt 9 ];then
msg="GOOD EVENING"
else
msg="GOOD NIGHT"
fi
echo "$msg ,CURRENT TIME $HH:$time"
exit 1
else
if [ $HH -lt 5 ];then
msg="GOOD NIGHT"
else
msg="GOOD MORNING"
fi
echo "$msg ,CURRENT TIME $HH:$time"
exit 1
fi

Write a script to display the name of those files (in the given directory) which are having multiple links.

clear
echo "Enter Directory Name :="
read dir
len=`ls -l $dir | wc -l`
i=2
echo "File With Multiple Link are : "
echo " "
while [ $i -le $len ]
do
record=`ls -l $dir | head -n $i | tail -n 1`
filename=`echo $record | cut -d " " -f 9`
link=`echo $record | cut -d " " -f 2`
if [ $link -gt 1 ];then
echo "$filename = $link"
fi
i=`expr $i + 1`
done

Write a script to delete zero sized files from a given directory (and all its sub-directories).

[[ METHOD 1 ]]

clear
`echo ls`>filelist
echo "==============="
total=`cat filelist | wc -w`
echo "total = $total"
i=$total
while [ $i -ge 1 ]
do
# temp=`expr $total - 1`
file=`tail -n $i filelist | head -n 1`
i=`expr $i - 1`
size=`ls -s $file|cut -c 1-2`
# echo "$size"

Write a JavaScript that finds out multiples of 10 in 0 to 10000. On the click of button start the timer and stop the counter after 10 seconds. Display on the screen how many multiples of 10 are found out within stipulated time.
