30 ln 建立一個到目標文件的鏈接(link)


–backup[=CONTROL] make a backup of each existing destination file.
-b like –backup, but does not accept an argument.
-d-F–directory allow the superuser to attempt to hard link directories (although it will probably fail due to system restrictions, even for the superuser).
-f–force remove existing destination files.
-i–interactive prompt whether to remove destinations.
-L–logical dereference TARGETs that are symbolic links. In other words, treat the symbolic link target as a file, not a link to a target.
-n–no-dereference treat LINK_NAME as a normal file if it is a symbolic link to a directory.
-P–physical make hard links directly to symbolic links.
-r–relative create symbolic links relative to link location.
-s–symbolic make symbolic links instead of hard links.
-S–suffix=SUFFIX override the usual backup suffix.
-t–target-directory=DIRECTORY specify the DIRECTORY in which to create the links.
-T–no-target-directory always treat LINK_NAME as a normal file.
-v–verbose print name of each linked file.
–help display a help message and exit.
–version output version information and exit.
