chmod command is used to change file permissionsyntax : chmod category operation permission filenamewhere category may be u = user ,g = group,o = others,a = alloperation may be '+' = assign permission,'-' = remove permission,'=' = exact permissionpermission may be r=read,w=write,x=executeEg: $chmod a+x file1 (give execute permission of file1 to all)

The last answer is correct and perfect explaination except to the fact that its not the user but the owner who first of all are provided with the rights

By default its 644 and this default value is stored in umask variable for any file that the terminal user sets for his particular case.This value is stored in umask in OCTAL form that makes it 0022.

the best was is to use CHOWN

Example:

chown owner:group <file_name>

chown -R owner:group <directory_name> <---- This will change the owner and group of all the files inside the directory recursively.
