Lineos:falseCopy the code code as follows: #!/bin/Bashsource=" $" while[-H"$SOURCE"]; Do# resolve $SOURCE until the file isno longer a symlink DIR="$ (cd-p"$ (dirname"$SOURCE")"&& pwd)"SOURCE="$ (Readlink"$SOURCE")"[[$SOURCE!=/*]] && source= "$DIR/$SOURCE" # If $SOURCE is a relative symlink, we need to resolve it relative to the path Where the symlink file was locateddonedir= "$ (cd-p" $ (dirname "$SOURCE") "&& pwd)"
