You can do that with a little script like the one i have written for you. It will start over and wait for input as long as Input is non-zero. If it is it will terminate.
Note that the script makes no efforts to validate the input - entering a string or another nonsensical value instead of an (integer) number will cause a error message by the shell.
Code:
#! /bin/ksh
typeset -i iLen=0
typeset -i iHgt=0
typeset -i iPrc=0
while : ; do
read iLen?"Enter length: "
if [ $iLen -le 0 ] ; then
exit 0
fi
read iHgt?"Enter height: "
if [ $iHgt -le 0 ] ; then
exit 0
fi
read iPrc?"Enter price : "
if [ $iPrc -le 0 ] ; then
exit 0
fi
print - "\nProduct (Length x Height x Price) is: $(( iLen * iHgt * iPrc ))"
print - "\n\n"
done
exit 0
Save this as "multiply.sh", do a "chmod 755 multiply.sh" and start it with "./multiply.sh".
I need to multiply the value of a variable and then store it in another variable. I have EXPHOURINSEC=$(($EXPDATEHOUR * 3600)) but i get an error saying the * is unexpected.

Hi,
I need to multiply 3rd column (comma seperated) of entire file by a value say 2.2.
Suppose the file is:

tkvars
tkvars(3tk) Tk Built-In Commands tkvars(3tk)__________________________________________________________________________________________________________________________________________________NAME
tkvars - Variables used or set by Tk
_________________________________________________________________DESCRIPTION
The following Tcl variables are either set or used by Tk at various times in its execution:
tk_library This variable holds the file name for a directory containing a library of Tcl scripts related to Tk. These scripts include
an initialization file that is normally processed whenever a Tk application starts up, plus other files containing proce-
dures that implement default behaviors for widgets. The initial value of tcl_library is set when Tk is added to an inter-
preter; this is done by searching several different directories until one is found that contains an appropriate Tk startup
script. If the TK_LIBRARY environment variable exists, then the directory it names is checked first. If TK_LIBRARY is not
set or does not refer to an appropriate directory, then Tk checks several other directories based on a compiled-in default
location, the location of the Tcl library directory, the location of the binary containing the application, and the current
working directory. The variable can be modified by an application to switch to a different library.
tk_patchLevel Contains a decimal integer giving the current patch level for Tk. The patch level is incremented for each new release or
patch, and it uniquely identifies an official version of Tk.
tk::Priv This variable is an array containing several pieces of information that are private to Tk. The elements of tk::Priv are
used by Tk library procedures and default bindings. They should not be accessed by any code outside Tk.
tk_strictMotif This variable is set to zero by default. If an application sets it to one, then Tk attempts to adhere as closely as possi-
ble to Motif look-and-feel standards. For example, active elements such as buttons and scrollbar sliders will not change
color when the pointer passes over them.
tk_textRedraw
tk_textRelayout
These variables are set by text widgets when they have debugging turned on. The values written to these variables can be
used to test or debug text widget operations. These variables are mostly used by Tk's test suite.
tk_version Tk sets this variable in the interpreter for each application. The variable holds the current version number of the Tk
library in the form major.minor. Major and minor are integers. The major version number increases in any Tk release that
includes changes that are not backward compatible (i.e. whenever existing Tk applications and scripts may have to change to
work with the new release). The minor version number increases with each new release of Tk, except that it resets to zero
whenever the major version number changes.
