DESCRIPTION

ns_chmod filename mode
Change a file's access permissions. ns_chmod changes the specified file's permissions to mode, in the same manner as the Unix chmod(1) command-line utility.

ns_cp -preserve file1 file2
Copy one file to another. ns_cp copies the contents of file1 to file2, just like the Unix "cp" command. The default directory is the home directory for the server. If -preserve is specified, the copied file will retain the creation time, modification time, owner, and mode of the original file, just like the Unix "cp -p" command.

ns_cpfp fileid1 fileid2 ?nbytes?
Copy a specified number of bytes from one file to another. ns_cpfp copies information from one file (fileid1) to another (fileid2). If you specify a number of bytes in the nbytes argument, only the specified number of bytes will be copied. By default, the entire file is copied.

ns_ftruncate fileid ?length?
Truncate an open file to a specified length. ns_ftruncate causes the open file specified by fileid to have a size of length bytes. If length is not specified, it causes the file to have a size of zero bytes. The file must be open and be a regular file.

ns_link ?-nocomplain? filename1 filename2
Create a link. ns_link creates a link named filename2 that points to the file specified by filename1. If the link fails, a Tcl error is generated, unless -nocomplain is specified.

ns_mkdir path
Create a directory. ns_mkdir creates the directory named PATH, just like the Unix mkdir command. By default, under Unix the directory is created with the file permissions set to 0755 (rwxr-xr-x.). These permissions can be modified by setting the umask parameter for the server.

ns_rename file1 file2
Rename a file. ns_rename renames the first file (file1) to the file name specified by file2. Make sure that the files and the directories in which the files exist are read/write accessible to the username that's running the AOLserver.

ns_rmdir path
Remove a directory. ns_rmdir removes the directory named path, just like the Unix rmdir command. The directory must already be empty.

ns_unlink [-nocomplain] filename
Remove a file. ns_unlink attempts to remove the file filename. If -nocomplain is not passed in and the removal fails, a Tcl error is generated.

ns_truncate filename ?length?
Truncate a file to a specified length. ns_truncate causes the file specified by filename to have a size of length bytes. If length is not specified, it causes filename to have a size of zero bytes. The file must exist and be a regular file.

ns_unlink [-nocomplain] filename
Remove a file. ns_unlink attempts to remove the file filename. If -nocomplain is not passed in and the removal fails, a Tcl error is generated.
