http://unix.stackexchange.com – Possible Duplicate: Why does this compound command report errors when copying directories? if one executes the following two commands in one line, as follows, rm -rf dir ; cp -r dir2 dir it may complain that cp can not create directory dir/subdir: File exists but if these two commands are executed in two lines, no errors will be thrown. I am just wandering what is the difference? and more importantly, how to execute two commands in one line, with the effect exactly the same as by two lines... PS: what is in dir or dir2 is hugh, typically 4gb (HowTos)

df in Fedora 17 !!! 7 weeks 2 days ago

Anybody uses Fedora 17/18 please try this testing: create 4 directories: % sudo su - % mkdir /dir1 /dir2 /mnt/dir1 /mnt/dir2 exportfs and mount your dir1 and dir2 to your server (the same server: mylinux)

add 2 lines in /etc/exports to export: /dir1 mylinux(ro) /dir2 mylinux(ro)

add 2 lines in /etc/fstab to mount: mylinux:/dir1 /mnt/dir1 nfs noauto,ret

By Rand Whitehall In the Linux command line shell, moving around from directory to directory, adding new directories, and deleting old directories is easy once you know the proper commands. Again, with Linux, you are limited only by your brain! If you know all the commands, then you weild great power.

I have 2 directories

DIR1 contains file1, file2 DIR2 contains file1, file3

Is there a way to replicate DIR1 to DIR2. means, if i give,

cp -r DIR1/* DIR2

file1 in DIR2 gets replaced with file1 in DIR1. file2 in gets copied to DIR2. file3 remains untouched.

But, i need DIR2 to be the exact replica of DIR1.

`os.symlink` vs `ln -s` 12 weeks 5 days ago

I need to create a symlink for every item of dir1 (file or directory) inside dir2. dir2 already exists and is not a symlink.

I've a problem copying many files in different directories. Let me explain better:

Let's say I have the following in a dir:

$ ls file1 file2 file3 file4 file5 dir1 dir2 dir3

and I want to copy every file* in every dir* with a single command.

We're quite fond of the style of the ebegin, eend, eerror, eindent etc commands used by Portage and other tools on Gentoo.

Hi,

I want to know how to find the latest modified directory. I know that the command 'ls -rtl' gives the latest modified file/directory at the end.

But my specific requirement is: If I create two directories named dir1, dir2 in the same order. so now my latest modified directory is "dir2". Now inside each directories, I created a file.
