There are too many lines of Linux Symbolic connections. When creating a symbolic link in linux n, you must use an absolute path. For example: /usr/local/cxxt/config-tools must be created to/usr/bin/config-tools. If your current directory is under the cxxt directory, run ln-s. /config-tools/usr/bin/config-tools at this time, run the config-tools symbol to connect too many layers. Use the ln command to use the absolute path to enable ln-s/usr/local/cxxt. /config-tools/usr/bin/config-tools ln command purpose: link file. Syntax 1> link a file to a file ln [-f |-n] [-s] SourceFile [TargetFile] 2> link one or more files to a directory ln [-f |-n] [-s] SourceFile... The TargetDirectory description ln command links the Files specified in the SourceFile parameter to the Files specified in the TargetFile parameter, or links them to files in another directory specified in the TargetDirectory parameter. By default, the ln command creates a hard link. If you need to use the ln command to create a symbolic link, specify the-s flag.
