floating point not recognized by printf in bash
Dear all,

I have the following question. Let's say that I have the following script

Code:
#!/bin/bash
value=0.4987865
a=` printf "%6.2f" $value `
b=`echo $value + $value | bc -l`
echo $a
echo $b
exit

And the exit is:

Code:
0,00
.9975730

Thus, the problem is that the printf order does not recognize the floating point arithmetic. Is there any way to fit this? In other machines it has always worked to me. Thanks in advace.

Floating Point Division

Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5). I am trying to do this using... (1 Reply)

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
