Top Forums Shell Programming and Scripting how can i do some action when 'ctrl+d' is pressed Post 302352190 by Scrutinizer on Thursday 10th of September 2009 04:06:42 PM

You use 01 02 03 04 .. 07 as array indices, which is unusual. I suspect these number get interpreted as octal numbers instead of decimal numbers, hence 08 would be to big for the base and it should be 10 (equals decimal 8).

mknod(5)							File Formats Manual							  mknod(5)

NAME
mknod.h - header file of macros for handling device numbers SYNOPSIS
DESCRIPTION
The header file defines macros to create and interpret device identification numbers for use with the system call (see mknod(2)). The use of these macros is architecture-dependent. See the System Administration Manual for your system for information on how to select major and minor device numbers. contains the macro which packs the major and minor components into a device identification number suitable for the dev argument of and the two macros: which extract the major and minor number components, respectively, from a device identification number, dev. The macro is a specification (see printf(3S)) that prints the minor number in the format best suited to the particular implementation; it is used by the long format of the command (see ls(1)) to show the minor numbers for device files. The base of the number is indicated in the same way as in the C programming language: no leading zero for decimal, leading zero for octal, and leading for hexadecimal. SEE ALSO
ls(1), mknod(1M), mknod(2), printf(3S). mknod(5)
