Hi all,
Im trying to do multiple things in one script..
firstly ...i am trying to call another script in one script...
secondly i am redirecting the output of second script in one file.
thirdly i am also using tail -f after the calling of 2nd script.
fourthly, all this is implemented in case under do while loop.
the problem is ...i can get to see details of tail -f...but cannot return to choices i have put using the CASE .
a.sh
Code:
while :
do
echo "please enter 1 to see Blah or 2 to see 2nd script or 3 to exit"
read ans
case $ans in
1)
echo "hello this is the first script"
;;
2)
echo "this will call another script"
cd to the location of second script
./b.sh > b.out
tail -f b.out
#:wall: this is where the script stops...i dont get back to the choices!!! and i have to press ctrl + c :(
;;
3)
exit
;;
*)
echo "wrong input"
;;
esac
done
b.sh
Code:
echo "hello this is second script"
db2 connect to database user username using password
db2 "select * form abc.abc_xyz with ur"
echo "done"
Kindly help me...wherin i can view the execution of the db2 command...as well as get back to the options i have given using case.
well, the -f switch of tail(1) will make it enter an infinite loop. So what exactly are you trying to do with that tail command?
Maybe less(1) would be more appropriate to view the contents of the stored output?
I want to see the execution of the second script, since it will go on for like 5 mins with lots of log messages and updation success or failed messages.
so after the second script is done executing, it should take me back at that place where in i can again input either 1 , 2 or 3
This helped a lot...Thanks...now as soon as the second script is done...i press 'q'...and then i can continue with the other choices!...
Thanks again!!
Yeah. Glad to be of help. Not only you can exit gracefully, less(1) provides a way to search for patterns through pressing '/' and specifying a regex, and other cool stuff, so you can scrutinize your output more efficiently
hey mirni...if you can help...
now when i get a statement like "updation successful" while executing the 2nd script, how do i write a if else statement as follows..
Code:
if ("updation successful" string is in the .out file) then
do something
else
something gone wrong
