I'm struggling to understand the man page entry about xargs in conjunction with the option -I. It states:
Quote:
Execute utility for each input line, replacing one or more occur-
rences of replstr in up to replacements (or 5 if no -R flag is
specified) arguments to utility with the entire line of input
And the description reads:
Quote:
The xargs utility reads space, tab, newline and end-of-file delimited
strings from the standard input and executes utility with the strings as
arguments.
Am I correct interpreting that as the fact that if no specified otherwise xargs -I can pass to a command following it no more than 5 arguments (a.k.a "strings") each of them containing unlimited number of occurrences of the data to be replaced using that command?
Furthermore what is a string in UNIX?
Example:
pass a list of highest level objects of current directory to some command
Does ls return one string comprising multiple lines? How many arguments that passes for? Or is one line = 1 string? 1 argument?

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)

GIT-PACK-REDUNDANT(1) Git Manual GIT-PACK-REDUNDANT(1)NAME
git-pack-redundant - Find redundant pack files
SYNOPSIS
git pack-redundant [ --verbose ] [ --alt-odb ] < --all | .pack filename ... >
DESCRIPTION
This program computes which packs in your repository are redundant. The output is suitable for piping to xargs rm if you are in the root of
the repository.
git pack-redundant accepts a list of objects on standard input. Any objects given will be ignored when checking which packs are required.
This makes the following command useful when wanting to remove packs which contain unreachable objects.
git fsck --full --unreachable | cut -d ' ' -f3 | git pack-redundant --all | xargs rm
OPTIONS --all
Processes all packs. Any filenames on the command line are ignored.
--alt-odb
Don't require objects present in packs from alternate object directories to be present in local packs.
--verbose
Outputs some statistics to stderr. Has a small performance penalty.
