Pehea ʻoe e hoʻololi ai i kahi loulou hōʻailona ma Unix?

Contents

No ka wehe ʻana i kahi loulou hōʻailona, ​​e hoʻohana i ke kauoha rm a i ʻole unlink i ukali ʻia e ka inoa o ka symlink ma ke ʻano he hoʻopaʻapaʻa. I ka wehe ʻana i kahi loulou hōʻailona e kuhikuhi ana i kahi papa kuhikuhi, ʻaʻole e hoʻopili i kahi slash hope i ka inoa symlink.

A laila, ʻekolu mau ala e hoʻololi ai i ka symlink:

  1. E hoʻohana i ka ln me -f ikaika a no nā papa kuhikuhi -n (hiki ke hoʻohana hou ʻia ka inode): ln -sfn /some/new/path linkname.
  2. Wehe i ka symlink a hana i kahi hou (ʻoiai no nā papa kuhikuhi): rm linkname; ln -s /kekahi/new/alanui linkname.

UNIX Symbolic link a i ʻole Symlink Tips

  1. E hoʻohana i ka ln -nfs e hoʻololi i ka loulou palupalu. …
  2. E hoʻohana i ka pwd i ka hui pū ʻana o UNIX soft link e ʻike i ke ala maoli e kuhikuhi ana kāu loulou palupalu. …
  3. No ka ʻike ʻana i nā loulou palupalu UNIX āpau a me nā loulou paʻakikī i kekahi papa kuhikuhi e hoʻokō ma hope o ke kauoha "ls -lrt | grep “^l” “.

Answer. What happens to symlink if we rename a file ? Once you move a file to which symlink points, symlink is broken aka dangling symlink. You have to delete it and create new one if you want to point to the new filename.

No ka nānā ʻana i nā loulou hōʻailona ma kahi papa kuhikuhi:

  1. E wehe i kahi kikowaena a neʻe i kēlā papa kuhikuhi.
  2. E kikokiko i ke kauoha: ls -la. E papa inoa kēia i nā faila a pau i loko o ka papa kuhikuhi inā ua hūnā ʻia.
  3. ʻO nā faila e hoʻomaka me l, ʻo ia kāu mau faila loulou hōʻailona.

Hiki ke hoʻoneʻe ʻia nā loulou hōʻailona me nā kauoha ʻelua: rm a unlink. Hiki iā ʻoe ke hoʻohana i kekahi o kēia mau kauoha e wehe i nā loulou hōʻailona. rm: ʻo ia ke kauoha hope e wehe i kēlā me kēia faila i hāʻawi ʻia me nā loulou hōʻailona. No ka mea ua manaʻo ʻia kahi loulou hōʻailona ma ke ʻano he faila ma Linux, hiki iā ʻoe ke holoi iā ia me ke kauoha rm.

With Windows Link Shell Extension installed, you can right-click on the link in Windows Explorer and check the properties. There is a tab that allows you to change the link directly.

No ka hana ʻana i nā loulou paʻakikī ma kahi ʻōnaehana Linux a i ʻole Unix-like:

  1. E hana i ka loulou paakiki ma waena o sfile1file a me link1file, holo: ln sfile1file link1file.
  2. No ka hana ʻana i nā loulou hōʻailona ma kahi o nā loulou paʻakikī, e hoʻohana: ln -s kumu loulou.
  3. No ka hōʻoia ʻana i nā loulou palupalu a paʻakikī paha ma Linux, holo: ls -l source link.

When you delete the source for a symbolic link the symbolic link is removed as well?

When you delete a file it removes one link to the underlying inode. The inode is only deleted (or deletable/over-writable) when all links to the inode have been deleted. A symbolic link is a link to another name in the file system. Once a hard link has been made the link is to the inode.

No ka hana ʻana i kahi loulou hōʻailona e hāʻawi i ke koho -s i ke kauoha ln a ukali ʻia e ka faila i kuhikuhi ʻia a me ka inoa o ka loulou. Ma kēia hiʻohiʻona e hoʻopili ʻia kahi faila i loko o ka waihona bin. Ma ka laʻana aʻe, ua hoʻopili ʻia kahi drive waho i kau ʻia i kahi papa kuhikuhi home.

ʻO kahi loulou hōʻailona, ​​i kapa ʻia hoʻi he loulou palupalu, he ʻano faila kūikawā e kuhikuhi ana i kahi faila ʻē aʻe, e like me ka pōkole ma Windows a i ʻole Macintosh alias. ʻAʻole like me kahi loulou paʻakikī, ʻaʻole i loaʻa i kahi loulou hōʻailona ka ʻikepili i ka faila i hoʻopaʻa ʻia. Kuhi wale ia i kahi komo ʻē aʻe ma kahi o ka ʻōnaehana faila.

ʻO kahi loulou paʻakikī kahi faila e kuhikuhi ana i ka inode lalo, me kahi faila ʻē aʻe. Inā hoʻopau ʻoe i hoʻokahi faila, wehe ia i kahi loulou i ka inode lalo. ʻOiai ʻo kahi loulou hōʻailona (ʻike pū ʻia ʻo ka loulou palupalu) he loulou i kahi inoa faila ʻē aʻe ma ka waihona.

Inā holoi ʻia kahi loulou hōʻailona, ​​ʻaʻole pili ʻia kāna pahuhopu. Inā kuhikuhi ka loulou hōʻailona i kahi pahu hopu, a i kekahi manawa ma hope ua hoʻoneʻe ʻia kēlā pahu hopu, kapa hou ʻia a holoi ʻia paha, ʻaʻole i hoʻonui ʻia a holoi ʻia ka loulou hōʻailona, ​​akā hoʻomau mau a kuhikuhi i ka pahu hopu kahiko, i kēia manawa he wahi ʻole a i ʻole. waihona.

E loaʻa paha nā loulou hōʻailona hōʻailona i nā mahele ala, kahi (inā hoʻohana ʻia ma ka hoʻomaka ʻana o ka pilina) e kuhikuhi i nā kuhikuhi papa a nā makua i kahi e noho ai ka pilina. Hiki i kahi pili hōʻailona (i ʻike ʻia he loulou palupalu) i kahi faila i loaʻa ʻole i kekahi mea ʻole; ʻike ʻia ka hopena hope loa ma ke ʻano he pilina koa.

ʻO ka loulou hōʻailona (Symlinks/Soft links) nā loulou ma waena o nā faila. ʻAʻole ia he mea pōkole wale nō o kahi faila (ma nā huaʻōlelo windows). … Akā inā e holoi ʻoe i ka faila kumu o ka symlink, ʻaʻole e hana hou ka symlink o kēlā faila a i ʻole lilo ia i "loulou pili" e kuhikuhi ana i kahi faila ʻole. Hiki ke hoʻopaʻa ʻia ka loulou ma ka ʻōnaehana waihona.
