Also, you need a loop for the menu since 'return' doesn't do what you think it does -- it quits the script just like exit does when used there.
Code:
REPLY="Y"
while [ "$REPLY" = "y" ] || [ "$REPLY" = "Y" ]
do
...
done
thx for your help, and what about the last 2 requirements in question one that is "The long listing of the directory specified by the first command line argument, sorted in reversed alphabetic order.
If the second command line argument is provided, all the above output will be redirected to the file specified by the second argument. If the second argument is not provided, the above output should be displayed on the screen. "and the 2nd question? I have no idea about these 2.

You've left out lots of spaces everywhere and put in semicolons you don't actually need:
Code:
# wrong
if[$n -lt 45];
# right
if [ "$n" -lt 45 ]
You also forgot to use $e here, used the wrong logic(you want || for 'or', since a string can never be 'y' and 'Y' at the same time). Also, -eq is for integers, for strings you want = .
Code:
if [ "$e" = 'y' ] || [ "$e" = 'Y' ]
But I think that bit would be simpler as a case:
Code:
case "$e" in
[yY]) exit
;;
[nN]) return
;;
esac
it shows "head:illegal line count -- Rail-Stations.txt"
and when I fix the 3rd part of the program,like this :
Code:
#!/bin/sh
echo "This is your username:" $USER
echo "This is the path of your login directory:" $HOME
cal 2012
echo "The amount of files in your directory are:";(ls ~|wc -l)
read n
if [ "$n" -lt 45 ];
then
head -n Rail-Stations.txt
fi
echo "Exit?(y/n)"
read e
if [ "$e" = 'y' ] || [ "$e" = 'Y' ];
then exit
if [ "$e" = 'n'] || [ "$e" = 'N' ];
return
fi
fi
it shows this :
Code:
Exit?(y/n)
y
./ass4: line 18: syntax error near unexpected token `fi'
./ass4: line 18: `fi'

Hi,
I want to write a script which will tail a particular file for 15 mins and then sleep for 10 mins and again tail for 15 mins. This cycle will go on for a limited period of time.
How can i ensure that tail command will run for 15 mins before calling sleep command
Thanks (6 Replies)
