Can I use xargs to send a list of commands to a process, to be acted upon individually? Here's what I have: a file that contains numbers, one per line. The desired outcome it to send each number to a DB2 query. I thought xargs would work, but it doesn't. I tried it like this:

I discovered that GNU's xargs has a -P option to allow its processes to run in parallel. Great! Is this a GNU thing, or is it supported by other platforms as well? (4 Replies)

ldd
LDD(1) BSD General Commands Manual LDD(1)NAME
ldd -- list dynamic object dependencies
SYNOPSIS
ldd [-a] [-v] [-f format] program ...
DESCRIPTION
The ldd utility displays all shared objects that are needed to run the given program or to load the given shared object. Contrary to nm(1),
the list includes ``indirect'' dependencies that are the result of needed shared objects which themselves depend on yet other shared objects.
Zero, one or two -f options may be given. The argument is a format string passed to rtld(1) and allows customization of ldd's output. If
one is given, it sets LD_TRACE_LOADED_OBJECTS_FMT1. If two are given, they set LD_TRACE_LOADED_OBJECTS_FMT1 and
LD_TRACE_LOADED_OBJECTS_FMT2, respectively. See rtld(1) for details, including a list of recognized conversion characters.
The -a option displays the list of all objects that are needed by each loaded object. This option does not work with a.out(5) binaries.
The -v option displays a verbose listing of the dynamic linking headers encoded in the executable. See the source code and include files for
the definitive meaning of all the fields.
EXAMPLES
The following is an example of a shell pipeline which uses the -f option. It will print a report of all ELF binaries in the current direc-
tory, which link against libc.so.6:
find . -type f | xargs -n1 file -F ' ' | grep ELF | cut -f1 -d' ' | xargs ldd -f '%A %o
' | grep libc.so.6
SEE ALSO ld(1), nm(1), rtld(1)HISTORY
A ldd utility first appeared in SunOS 4.0, it appeared in its current form in FreeBSD 1.1.
The -v support is based on code written by John Polstra <jdp@polstra.com>
