How to copy any files or directories from one user to another user in a same machine via terminal?

Suppose there is one file test.txt in home directory of USER1. I need to copy that file to the home directory of USER2 in my machine. How can I do it via terminal?


Assuming that you have sudo privileges the following command will do.

sudo cp /home/USER1/FNAME /home/USER2/FNAME && sudo chown USER2:USER2 /home/USER2/FNAME

Will copy the file from USER1 to USER2, and then change the owner of the copy in /home/USER2 to USER2

If you do not have sudo privileges, then the two users will need to ensure that you have read permissions on the USER1 directory, and write access on the USER2 directory. If you have these accesses, you can enter the command:

cp /home/USER1/FNAME /home/USER2/FNAME

This will copy the file in question, but USER2 may not be able to manipulate the file until they have appropriate permissions.

  • This will work only if USER1 has sudo access, which might not be the case in a multiuser system. – BostonHiker Nov 18 '14 at 15:24
  • The other option would be to set the permissions on their own folder to allow the other user to grab them, but this option is much easier if possible. – Geary Shull Nov 18 '14 at 15:29
  • @BostonHiker I had made the assumption that the person doing the copy is neither USER1 or USER2, and has sudo priviledges. This is probably a poor assumption on my part. – Charles Green Nov 18 '14 at 16:10
  • @Charles Green - please edit your answer to state your assumptions, otherwise it is incomplete/misleading. – BostonHiker Nov 18 '14 at 16:19
  • @BostonHiker Done. Thanks for keeping me honest. – Charles Green Nov 18 '14 at 17:48


cp [filename] /tmp
chmod 777 /tmp/[filename]


cp /tmp/[filename] .


rm /tmp/[filename]

if you dont have sudo privileges but you can login with the two users then you can use scp with localhost :

scp file1 user2@localhost:/home/user2/
  • What makes you think that this is about a remote host or that there's an SSH/SFTP server running on the machine in question? – David Foerster Jan 12 '17 at 13:26

    Assuming you have SSH installed – loudstil Feb 14 '17 at 15:09

Assume you either do not have ssh installed, or cannot do do not want to share keys/secrets.

Suppose user1 is in group1, and user2 is in group2, and both user1 != user2 and group1 != group2.

Create a shared group, group3s.

addgrp group3

Add both user1 and user2 to group3s.

Create a directory in a mutually accessible place, where one user owns, but has group ownership of group3s.

#as user1,
mkdir $place/shared && chown user1.group3s $place/shared && chmod 770 $place/shared;
#as user1 or user2,
cp $file $place/shared && chgrp $place/shared/$file && chmod 660 $place/shared/$file

But, suppose you cannot create the new, shared group, and place both users in that group?

Create the directory and give it 770 permissions,

mkdir $place/shared && chown user1.group1 $place/shared && chmod 770 $place/shared;

Then, as root/admin, change the group ownership to the other user's group,

sudo bash
chgrp group2 $place/shared && chmod g+s $place/shared

The command chmod g+s sets the setgid bit so that files placed into the directory have the group ownership set to group2.


Every other answer here requires root access, allows any user on the same machine to copy the file, or requires password sharing. Here is a method that does not:

Have USER2 (let's call him Bob) run the following commands (you can replace /tmp with any directory that both users have permissions to write to, but /tmp is ideal because by default it is sticky, which prevents a malicious user from subverting this process. A directory owned by Bob that is world-readable also works):

[bob@computer ~]$ touch /tmp/test.txt
[bob@computer ~]$ chmod 622 /tmp/test.txt

This creates a file that is world-writable, but not readable.

Then have USER1 (let's call her Alice) run (if you're paranoid, Alice can check the permissions first to make sure the file is owned by Bob):

[alice@computer ~]$ dd if="$HOME/test.txt" of=/tmp/test.txt

This overwrites the contents of /tmp/test.txt. If you want to check integrity of the file, Alice should also generate a hash of the file. For instance:

[alice@computer ~]$ openssl sha1 < "$HOME/test.txt" > /tmp/test.txt.sha1

You can instead digitally sign the file, or any other method of guaranteeing its integrity.

And finally Bob moves the file and takes ownership of it:

[bob@computer ~]$ mv /tmp/test.txt "$HOME" 
[bob@computer ~]$ chmod 600 "$HOME/test.txt"

And Bob can check the integrity if he likes. If so, he should check to make sure only Alice can write to /tmp/test.txt.

[bob@computer ~]$ diff /tmp/test/txt.sha1 <(openssl sha1 < "$HOME/test.txt")

If the file was copied correctly, this should display no output.


Before going to copy one user to another you need to login as su user and then you use the command cp

sudo cp /home/shyam/Desktop/sparkhadoop_2.11-1.0.jar /home/hadoop/Desktop
  • This won't transfer the ownership to USER2 but leave it as root though. -1 – David Foerster Nov 11 '17 at 17:49
  • @DavidFoerster we are not transferring the ownership, we copy the file from one user to another user. using root user, we can transfer the file. OK – Shyam Gupta Nov 11 '17 at 18:15
