Otu esi etinye asụsụ Lua Scripting na Linux

Lua bụ isi mmalite mepere emepe, dị ike, siri ike, nke pere mpe, yana asụsụ ederede nwere ike itinye. Asụsụ edemede nwere ike ịgbatị ma tụgharịrị ya bụ nke a na-ede nke ọma, ma na-agba ya site na ịsụgharị bytecode na igwe mebere ndebanye aha.

Lua na-agba ọsọ ma ọ bụrụ na ọ bụghị ọtụtụ sistemụ arụmọrụ Unix gụnyere Linux na Windows; na sistemụ mkpanaka mkpanaka (Android, iOS, brew, Symbian, Windows Phone); na microprocessors agbakwunyere (ARM na oke bekee); na IBM mainframes, na ọtụtụ ndị ọzọ.

Hụ ka mmemme Lua si arụ ọrụ na ngosi ngosi ndụ.

Otu esi etinye Lua na Linux

Ngwungwu Lua dị na ebe nchekwa ọrụ nke nkesa Linux bụ isi, ị nwere ike ịwụnye ụdị kachasị ọhụrụ site na iji njikwa ngwugwu kwesịrị ekwesị na sistemụ gị.

------- On Debian, Ubuntu & Mint ------- 
$ sudo apt install lua5.3

------- On RHEL, CentOS, Rocky & AlmaLinux ------- 
# yum install epel-release
# yum install lua

------- On Fedora Linux ------- 
# dnf install lua

Rịba ama: Ụdị ngwugwu Lua dị ugbu a na ebe nchekwa EPEL dị ntakịrị, ya mere iji wụnye ntọhapụ ọhụrụ, ịkwesịrị ịmepụta na wụnye ya site na isi iyi dị ka akọwara n'okpuru.

Nke mbụ, hụ na ị nwere akụrụngwa mmepe arụnyere na sistemụ gị, ma ọ bụghị ya, mee iwu dị n'okpuru iji wụnye ha.

------- On Debian, Ubuntu & Mint ------- 
$ sudo apt install build-essential libreadline-dev

------- On RHEL, CentOS, Rocky & AlmaLinux and Fedora ------- 
# yum groupinstall "Development Tools" 
# yum install readline readline-devel

Mgbe ahụ iji wuo ma wụnye ntọhapụ ọhụrụ (ụdị 5.4.4 n'oge ederede) nke Lua, ịkwesịrị ibudata faịlụ lua ma ọ bụ mee iwu ndị a ka ibudata ngwugwu tarball, wepụ, wuo ma wụnye ya.

$ mkdir lua_build
$ cd lua_build
$ curl -R -O http://www.lua.org/ftp/lua-5.4.4.tar.gz
$ tar zxf lua-5.4.4.tar.gz
$ cd lua-5.4.4
$ make linux test
$ sudo make install

Ozugbo itinyechara ya, mee ntụgharị Lua ka egosiri.
