Why does this compound command report errors when copying directories?

view full story
linux-howto

http://unix.stackexchange.com – 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... EDIT: I change it to cp -r dir2 dir. Besides, what is in dir or dir2 is huge, typically 4gb. (HowTos)

df in Fedora 17 !!! 2 weeks 6 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

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` 8 weeks 2 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 have multiple hard drives with the same directory hierarchy, for example:

/media/sda/dir1 /media/sda/dir2 ... /media/sdb/dir1 /media/sdb/dir2

Two hard drives with similar names and similar directory names. I want to create separate symbolic links to dir1 and dir2 on every hard drive. The easiest way I have found is to use cp -sR:

cp -sR /media/sd*/dir1 /somedir/dir1 cp -sR /media/sd*/dir2 /s

I have a list of relative paths such as this:

dir1 dir2 dir2/dir3 dir2/file1 dir3/file2 dir3/dir4 dir3/dir4/file3

In the example above, the specifier dir2/file1 (for example) is redundant, because the dir2 entry would include this file.

Want I want to do, essentially, is remove redundant paths from a given list of paths.

Hello All,

I am in the process of finding the permissions on all the files that exists in two directories:

Dir1: PROD_Scripts/* Dir2: STAGE_Scripts/*

Both the Directories have some shell and perl scripts respectively.

Step1: Finding all the Scripts that exists in PROD but Not in STAGE. I found out Using diff Dir1 Dir2 and got 17 Scripts that exists in PROD but not in STAGE

Step2:

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.
