This is a MUCH simpler problem than the problem the script you copied was trying to solve. To move a bunch of files from a single directory to a subdirectory of that same directory, all you need is something like:
You didn't answer whether you want to move files or copy files. The above code moves files; if you want to copy them instead, change mv to cp. If you want to make hard links to the files (giving each of the files two names) instead of moving them or copying them; change mv to ln.
I asked what systems other than cygwin running on Windows you wanted this script to work on. You said telnet, but telnet is a utility implementing a communications protocol to a remote system; it is not a type of system like Windows, UNIX, or Linux.
Hi all,
I wanted to know how i can copy a file to a directory and then verify if that file is completely copied or not?
Now the issues here is that the dir and the source file are to be sent as arguments to a function( this function should actually copy the files to a dir, then check if its... (0 Replies)

Hi,
I'm puzzled at how this could be.
I'm trying to transfer some files from an Sun box to an AIX box via FTP. The file transfer goes fine until it reaches a file of about 150k then times out and fails.
The FTP Does not seem to be able to transfer files of more than 150k! However, I can... (5 Replies)
Hello all.
I'm not getting the hang of Paths. I have a dir w/files that I want to copy to another dir. Right now I am in the "source" directory. I want to copy it to Ch7.
"cp -r source Ch7". Ch7 was already created.
1st msg.: cannot stat `source`: No such file or dir.
I typed pwd & got... (3 Replies)
Hi everyone. I am trying to write a bash script that will copy files from one directory to another but I need to be able to check the directory that I'm copying the files to and see if the file already exists. If it does I need to add a number at the end of the copied file. Thanks for your help. (3 Replies)
hi,
I want to copy files from source directory based on input file (or output of previous command) and i want to have the SAME DIRECTORY STRUCTURE.
Note that i will have other files and directories which i dont want to copy to destination.
For example, dir source has following content:... (22 Replies)
my user copy large files, and it's take 10min for file to be copied to the server (/tmp/user/ files/), if in the meantime start my scheduled script, then it will copy a part of some file to server1
my idea is to check the file size twice in a short period (1-2 seconds) of time, then compare, if... (5 Replies)
Hello Comunity
I am trying to make a bash shell script that it copies files and subdirs(with files) to a new dir. I would like the dest_dir to contain only subdirectories with files not other subdirs inside.
it called : cpflatdir src_dir dest_dir
Pleaze help me!
Thank you in... (2 Replies)
Using RCP command we can transfer file from one server to another server.
While transferring we can rename the file also e.g.
File name = FILE123.txt (lying on Source server = oldserver)
Target Server Name = newyour
Renamed File = FILE456.txt
rcp FILE123.txt newyour:./FILE456.txt... (1 Reply)

if n directory is not present at Q2/dir/folder1/expected/ then directory should be created first. And, script follow the... (5 Replies)

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
