Shell Programming and Scripting

Hi,

Requirement:-

I have 3 scripts(say A.sh,B.sh & C.sh).Now am executing these 3 scripts seperately.requirement is to run these 3 scripts as single from one main script,this script has to call A.sh and if A.sh executed completely,it has to invoke B.sh and like the 3 rd one.And while executing the 2nd script its asking one prompt
(eg:-Do you really want to rename(enter YES or NO)? ),there "YES" has to enter...how will this implement.please help...

Just put the scripts in the main script like you run from the command prompt.
All would be executed serially.

Code:

#! /usr/bin/ksh

/path/to/A.sh
/path/to/B.sh
/path/to/C.sh

About the prompt, Its not clear where you want to prompt? Is it inside script B.sh or in main script?

Where-ever it is, that should be something like below

Code:

echo -n "Do you really want to rename - YES/NO?"
read answer

if [ "$answer" = "YES" ]; then
 # steps
fi

I needed in past something like.... but:
Write script_1.sh and then inside it :

Xterm -e " . /script_2 ; killall xterm ; "
Xterm -e " . /script_3 ; killall xterm ; "
Xterm -e " . /script_4 ; killall xterm ; "
....

I hope this helps.

Code:

if [ "$answer" = "YES" ]; then 
 # steps 
fi

I would be more inclined to reverse the condition to:

Code:

if [  "$answer"  !=  "YES"  ]; then 
 exit 1
fi

While both work, I find that matching "if",s and "fi", that extend over a page or so of code to be error prone.

Hi Sanal

You can try this also..
Call first script in mail script (A.sh)

put B.sh in last line of A.sh , and likewise C.sh

If A.sh ran it will call B.sh and likewise...

Main Script
A.sh
B.sh
C.sh

hope it helps
