I would like to use a bash script to automate variable input process to update system FRU data under one entry. if I can use like set /p type command to stor diffenet variables in the memory then call out at the main command level under different parameters to exacute them at once.

Maybe this:

% read -p "My Msg: " Var
My Msg: my-val
% echo $Var
my-val
%

my google of:
bash prompt for input
returned:
http://stackoverflow.com/questions/2...x-shell-script

I tried
% read --help
which seems to be a shell "builtin", since
% which read
says none in /bin...
Also I found: http://wiki.bash-hackers.org/commands/builtin/read
( also see: % man [or info] set [vs. env] )

I'm not sure about the "execute" part: maybe eval $Var vs. `cmd` or $(cmd)
(I googled: shell execute variable backquote)

Does this 'solve' your question? (I was surprised to see my XP cmd: set /? gave several pages!)
Feel free to ask more specific/details; best wishes!

N/m I misunderstood what /p did.

thanks,
what I am trying to do in Windows was:
set /p pn=what is the device part number?
set /p sn=what is the device serial number?
set /p s=what is server number?

ipmiupdt -p %pn% -s %sn% -i %s$

so I can program the FRU data at once. And what is correct syntax in bash script?

lol.
instead of asking us to translate your windows commands line by line into bash, maybe you should just learn bash?
there's plenty of tutorials and wikis around the web, e.g. this one.

read -p "what ... num?" variablename
Then use $variablename instead of %variablename%

Sorry, I couldn't resist (I'm tired of booting my tinycore/dsl/nanolinux VBoxes & discovering that they aren't the SAME as RH/SUSE/Slackware, or watching Mint take an hour to boot)
