Why dont you run the ls command as:
and pipe the output to xargs.
The output of this will be the $Dir/file1 $Dir/file2 ... and so on. So you dont have to append anything anywhere..
Hi there,
I am trying to move around 3000 files from one directory to another. The mv command is complaining from too many arguments. I tried to use the xargs command but with no luck. Could some body provide help?

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)
Hi,
I have a requirement to RCP the files from remote server to local server.
Also the RCP has to run in parallel. However using 'xargs' retrives 2 file names during each loop. How do we restrict to only one file name using xargs and loop till remaining files.

Hello there,
Let me show you a simple example of what I am trying to achieve:
1) I have an input text file with some lines:
1 a
2 b
3 c
2) And I want to run a command with these lines as arguments (+ arbitrary extra arguments). For example:
$ command "1 a" "2 b" "3 c" "bye"

Hi,
What is the difference in capitalizing the option 'i' of xargs command, (i.e) xargs -i and xargs -I?
Also, what is the difference between the below 2 commands?
output_from_cmd | xargs -I {} grep '{}' file
output_from_cmd | xargs -I grep '{}' file
Any efficiency or performance... (4 Replies)

io::dir
IO::Dir(3pm) Perl Programmers Reference Guide IO::Dir(3pm)NAME
IO::Dir - supply object methods for directory handles
SYNOPSIS
use IO::Dir;
$d = new IO::Dir ".";
if (defined $d) {
while (defined($_ = $d->read)) { something($_); }
$d->rewind;
while (defined($_ = $d->read)) { something_else($_); }
undef $d;
}
tie %dir, IO::Dir, ".";
foreach (keys %dir) {
print $_, " " , $dir{$_}->size,"
";
}
DESCRIPTION
The "IO::Dir" package provides two interfaces to perl's directory reading routines.
The first interface is an object approach. "IO::Dir" provides an object constructor and methods, which are just wrappers around perl's
built in directory reading routines.
new ( [ DIRNAME ] )
"new" is the constuctor for "IO::Dir" objects. It accepts one optional argument which, if given, "new" will pass to "open"
The following methods are wrappers for the directory related functions built into perl (the trailing `dir' has been removed from the
names). See perlfunc for details of these functions.
open ( DIRNAME )
read ()
seek ( POS )
tell ()
rewind ()
close ()
"IO::Dir" also provides an interface to reading directories via a tied HASH. The tied HASH extends the interface beyond just the directory
reading routines by the use of "lstat", from the "File::stat" package, "unlink", "rmdir" and "utime".
tie %hash, IO::Dir, DIRNAME [, OPTIONS ]
The keys of the HASH will be the names of the entries in the directory. Reading a value from the hash will be the result of calling
"File::stat::lstat". Deleting an element from the hash will call "unlink" providing that "DIR_UNLINK" is passed in the "OPTIONS".
Assigning to an entry in the HASH will cause the time stamps of the file to be modified. If the file does not exist then it will be cre-
ated. Assigning a single integer to a HASH element will cause both the access and modification times to be changed to that value. Alterna-
tively a reference to an array of two values can be passed. The first array element will be used to set the access time and the second ele-
ment will be used to set the modification time.
