translate script with command od

cariteyp — Wed, 22 Feb 2006 08:46:48 GMT

Hi all,

I would like to use this function on HPUX, but od -D doesn't work on HP-UX.
Could oyu help me ?

Here the function :

GetLong()
{
# Returns 4-byte unsigned integer.
#
# Parameters:
# $1 - offset in the file;
# $2 - file to read.

# od -D Interpret long words in unsigned decimal:
od -D $2 +$1. | \
awk '{ printf"%d",$2; exit }'

} # GetShort()

Hi,
do a man od for full spec.
The -j option specifies the offset.

Sorry ...

The syntax you are using is pre-posix. The posix format would be-

od -t d4 filename

This would dump 4 bytes at a time of of signed decimal

od -t u4 filename

Would dump 4 bytes unsigned decimal

This is described in the "man od".
