Pehea wau e ʻike ai i nā loulou palupalu ma Linux?

Contents

E hoʻohana i ke kauoha ls -l e nānā inā he loulou hōʻailona ka faila i hāʻawi ʻia, a e ʻimi i ka faila a i ʻole ka papa kuhikuhi e kuhikuhi ai ka loulou hōʻailona. ʻO ka huaʻōlelo mua "l", e hōʻike ana he symlink ka faila. Hōʻike ka hōʻailona "->" i ka faila kahi e kuhikuhi ai ka symlink.

ls command to find a symbolic link in UNIX systems

If you combine the output of ls command with grep and use a regular expression to find all entries which start with small L than you can easily find all soft link on any directories. The ^ character is a special regular expression which means the start of the line.

Hiki iā ʻoe ke nānā inā he symlink kahi faila me [ -L file ] . Pēlā nō, hiki iā ʻoe ke hoʻāʻo inā he faila maʻamau ka faila me [ -f file ] , akā i kēlā hihia, hana ʻia ka nānā ma hope o ka hoʻoholo ʻana i nā symlinks. ʻAʻole ʻano faila nā hardlinks, he inoa ʻokoʻa wale nō ia no kahi faila (o kēlā me kēia ʻano).

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.

ʻAe, hāʻawi ke kauoha "ln -s" iā ʻoe i kahi hopena ma ka ʻae ʻana iā ʻoe e hana i kahi loulou palupalu. Hoʻokumu ka ln kauoha ma Linux i nā loulou ma waena o nā faila / papa kuhikuhi. ʻO ka hoʻopaʻapaʻa "s" e hoʻohālikelike i ka loulou ma kahi o ka loulou paʻakikī.

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.

He aha ka Soft Link a me ka Hard Link ma Linux? ʻO kahi loulou hōʻailona a palupalu paha kahi loulou maoli i ka faila kumu, akā ʻo ka loulou paʻakikī he kope aniani o ka faila kumu. Inā holoi ʻoe i ka faila kumu, ʻaʻohe waiwai o ka loulou palupalu, no ka mea, kuhikuhi ia i kahi faila ʻole.

The links in Unix are essentially the pointers which associate to the files and directories. The major difference between a hard link and soft link is that hard link is the direct reference to the file whereas soft link is the reference by name which means it points to a file by file name.

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” “.

ʻO ka hapa nui o nā ʻōnaehana waihona e kākoʻo ana i nā loulou paʻakikī e hoʻohana i ka helu kuhikuhi. Mālama ʻia kahi waiwai integer me kēlā me kēia ʻāpana ʻikepili kino. Hōʻike kēia integer i ka huina o nā loulou paʻakikī i hana ʻia e kuhikuhi i ka ʻikepili. Ke hana ʻia kahi loulou hou, hoʻonui ʻia kēia waiwai e hoʻokahi.

Pehea ʻoe e nānā ai inā he loulou hōʻailona ka papa kuhikuhi?

No ka hoʻoholo inā he loulou hōʻailona ka waihona, hiki iā ʻoe ke hoʻohana i kekahi o kēia mau ala.

  1. Hana GUI: E ʻokoʻa ke kiʻikona waihona. He pua ka ikona o ka waihona.
  2. Kaʻina CLI. ʻO ka hoʻopuka o ls -l e hōʻike maopopo ʻia he loulou hōʻailona ka waihona a e hoʻopaʻa inoa i ka waihona kahi e kuhikuhi ai.

program directory in a file manager, it will appear to contain the files inside /mnt/partition/. program. In addition to “symbolic links”, also known as “soft links”, you can instead create a “hard link”. A symbolic or soft link points to a path in the file system.

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.

ʻAe. Loaʻa iā lāua ʻelua ka hakahaka no ka mea, aia nō lāua i nā hoʻokomo papa kuhikuhi.

Ma ka paʻamau, hana ke kauoha ln i nā loulou paʻakikī. No ka hana ʻana i kahi loulou hōʻailona, ​​e hoʻohana i ke koho -s ( –symbolic). Inā hāʻawi ʻia ka FILE a me LINK, e hana ʻo ln i kahi loulou mai ka faila i kuhikuhi ʻia ʻo ka hoʻopaʻapaʻa mua ( FILE ) i ka faila i kuhikuhi ʻia ʻo ka pane ʻelua ( LINK ).
