Untuk mengaktifkan cd'ing ke folder alias saya telah menemukan yang berikut di Mac OS X Petunjuk .
Kompilasi kode sumber di bawah ini dengan perintah berikut:
gcc -o getTrueName -framework Carbon getTrueName.c
Ini akan membuat executable 'getTrueName' di direktori yang sama dengan sumbernya. Anda dapat menambahkannya ke PATH Anda, atau cukup salin langsung ke / usr / bin atau / usr / local / bin sehingga mudah diakses.
Kode sumber C untuk getTrueName (salin teks dan simpan file sebagai getTrueName.c di direktori home Anda):
// getTrueName.c
//
// DESCRIPTION
// Resolve HFS and HFS+ aliased files (and soft links), and return the
// name of the "Original" or actual file. Directories have a "/"
// appended. The error number returned is 255 on error, 0 if the file
// was an alias, or 1 if the argument given was not an alias
//
// BUILD INSTRUCTIONS
// gcc-3.3 -o getTrueName -framework Carbon getTrueName.c
//
// Note: gcc version 4 reports the following warning
// warning: pointer targets in passing argument 1 of 'FSPathMakeRef'
// differ in signedness

#include <Carbon/Carbon.h>
#define MAX_PATH_SIZE 1024
#define CHECK(rc,check_value) if ((check_value) != noErr) exit((rc))
int main ( int argc, char * argv[] )
{
FSRef fsRef;
Boolean targetIsFolder;
Boolean wasAliased;
UInt8 targetPath[MAX_PATH_SIZE+1];
char * marker;
// if there are no arguments, go away
if (argc < 2 ) exit(255);
CHECK( 255,
FSPathMakeRef( argv[1], &fsRef, NULL ));
CHECK( 1,
FSResolveAliasFile( &fsRef, TRUE, &targetIsFolder, &wasAliased));
CHECK( 255,
FSRefMakePath( &fsRef, targetPath, MAX_PATH_SIZE));
marker = targetIsFolder ? "/" : "" ;
printf( "%s%s\n", targetPath, marker );
exit( 1 - wasAliased );
}
Sertakan berikut ini di ~ / .bash_profile atau buat file baru ~ / .bash_profile dengan konten berikut:
function cd {
if [ ${#1} == 0 ]; then
builtin cd
elif [ -d "${1}" ]; then
builtin cd "${1}"
elif [[ -f "${1}" || -L "${1}" ]]; then
path=$(getTrueName "$1")
builtin cd "$path"
else
builtin cd "${1}"
fi
}
Anda mungkin harus memulai ulang Terminal untuk memuat .bash_profile Anda yang dimodifikasi.
Diuji dalam Yosemite 10.10.2 & gcc 4.2 (Xcode 6.2) dan berhasil.
