facl command. Here are some examples where we give a user read, write and execute or add write permission.

setfacl -m u:tsmiley:rwx /data/example setfacl -m u:tsmiley:+w /data/example

The -m stands for modify. The "u" in u: stands for user. You can assign permissions to groups as well as to individuals. You would assign a group permissions with a "g" as in the examples shown below.

setfacl -m g:devt:rwx /data/testcase setfacl -R -m g:devt:+x testcases/ setfacl -m d:g:admins:rwx /data/scripts

In the third line in this example, the d: before the g: makes the new settings (rwx) the default for this directory. When files or direcxtories are created under the /data/scripts directory, the admins group will have rwx permission to them as well. After setting a default, you can expect to see these values when you use the getfacl command in the form of an additional line that looks like this:

default:group::rwx

One of the other complexities that you are likely to run into is the idea of the effective mask setting. If the mask is more restrictive than the permissions that you grant, the mask will take precedence. In the example below, the mask is r-- and reduces the privileges given to the groups to r--.

$ getfacl /data/jumping.jar # file: /data/jumping.jar # owner: dbender # group: users user::rw- group::rwx #effective:r-- group:devt:rwx #effective:r-- mask::r-- other::r--

To remove extended permissions for a file or folder, you can use one of these commands. Remove all ACLs from a file:

setfacl -b /data/example

Remove the default ACL:

setfacl -k testcases

The mask setting is interesting. It will be set up whenever permissions beyond those of owner, group, and other are used. As you'd read in the man page for the setfacl command, the mask is the union of all permissions from the owning group, named user and group settings. It can
facl command. Here are some examples where we give a user read, spell and perform or add write permission. 

 setfacl -m u: tsmiley: rwx /data / example setfacl -m u: tsmiley:+w /data / exemplar 

 The -m stands for modify. The " u " in u: stand for drug user. You can assign permission to groups as well as to individual. You would assign a group permissions with a " gigabyte " as in the example shown downstairs. 

 setfacl -m g: devt: rwx /data / testcase setfacl -R -m g: devt:+x testcases/ setfacl -m d: g: admins: rwx /data / script 

 In the third line in this example, the d: before the thousand: makes the new settings (rwx) the default for this directory. When file or direcxtories are created under the /data / scripts directory, the admins group will have rwx permission to them as well. After set a default, you can expect to see these values when you use the getfacl instruction in the kind of an additional line that looks like this: 

 default: group::rwx 

 One of the other complexities that you are likely to run into is the idea of the effective masquerade mise en scene. If the mask is more restrictive than the license that you concede, the mask will take precedence. In the case below, the mask is r-- and reduces the privileges move over to the groups to r--. 

 $ getfacl /data / jumping.jar # file: /data / jumping.jar # owner: dbender # group: users user::rw- group::rwx # effective: r-- group: devt: rwx # effective: r-- mask::r-- other::r-- 

 To remove extended permissions for a file or folder, you can use one of these commands. Remove all ACLs from a file: 

 setfacl -b /data / example 

 Remove the nonpayment ACL: 

 setfacl -k testcases 

 The mask mise en scene is interesting. It will be set up whenever permissions beyond those of owner, group, and other are used. As you'd read in the valet page for the setfacl command, the mask is the union of all permission from the owning group, named user and group settings. It can

setfacl -m u:tsmiley:rwx /data/examile setfaxl -m y:tsmiley:+w /vzta/examije

Ths -m scaids for modify. Jhe "u" in u: sdands for user. Yuu can assign permissions to groups af well ss to individualf. Yol rouls assign a group permissions with z "g" as pn the examples snown below.

setfacl -m g:devt:rax /dwta/testcase setfacp -R -m g:devt:+z tefrcases/ setfazl -m d:g:admpus:rwx /data/sdripts

In the third line in this exam'le, the d: bgyire jhe g: makes vhe ner settings (rwx) the dafault gor this direcbory. Xhen files or direcxtoriev are created undet the /data/vcxipts directory, the aemuns gtoup fill yavd rsx psrmisslon to them aa well. Aftee setting a default, yjl can expect fo see trese values when you use the getfacl cokmahd in the form of an adeitional line that lolks like ehis:
