Hi All,
I am in Bash Shell and Running A script that contains Exit statement in that in last ( to return to sh shell after executing) But it is not coming to sh shell after the script is excuted.
How to return to sh shell from bash shell through a script.

If it doesn't return, what happens then? It just hangs up opr what? May be in the last lines of script some lengthy command is executing?

Post your script within code tags (select the code and click on the '#' above the edit window), and we'll see how we can assist.

Regards

Please post your code or use "sh -x scriptname " to see its execution to find out where it gets hang

Actually i m just redirecting the output of single command to a file name ( for the Database)

through a script

ping localhost > abc.sh$"$(date ' +%d%b%y')".lst
exit

Case1)
Bash-3.2#./abc.sh
Bash-3.2#

output)abc28Aug.lst == correct output===

Case2) #./abc.sh

output) abc$$(date '+%d%b%y').lst ===wrong output=====

After executing in a bash shell it should not come to bash shell ,
i want to run the script from the sh shell only ?

When you run any shell script it spawns a new shell, so including an exit statement will have no effect, you will still be returned to the parent shell that you run it from (unless you "source" the script using . ./abc.sh).

If you need to run the shell from sh, but have it interpreted by bash, then just add a shebang line as the first line of the script, e.g.

Also, I'm nost sure why you have the extra $"" around the date command, this should be enough:

Probably you end up running a different version of ping which just keeps on looping forever. Perhaps your PATH is different in Bash than in the regular Bourne shell. Try specifying an explicit pathname like /bin/ping or whatever works for you.

Some versions of ping accept an argument -c 1 which says to send only one packet and then quit (or any number after -c of course); if not specified, they will loop forever.

If your shell doesn't understand $(...) you can use `...` instead (those are grave accents -- ASCII 96 -- not regular straight apostrophes).
