Time	Narration
00:01	Ngi pdiangsngewbha ia phi sha ka spoken tutorial halor ka Basics of Shell Scripting.
00:05	Ha kane ka jinghikai, ngin pule shaphang:
00:09	System variables
00:11	User defined variables bad
00:13	Ban accept ia ka user input lyngba ka keyboard.
00:16	Ban bud ia kane ka jinghikai phi dei ban nang bad tip ia ka Linux Operating System.
00:23	Lada phim pat tip, te na ka bynta ki jinghikai ba iadei bad ka Linux, peit ia ka website jong ngi ba la pyni hangne
00:29	Na ka bynta kane ka jinghikai, nga pyndonkam:
00:32	Ubuntu Linux 12.04 OS bad
00:35	GNU Bash version 4.1.10
00:40	Sngewbha kynmaw, ka GNU Bash version 4 lane kiba kham shajrong la ai jingmut na ka bynta kane ka jinghikai
00:46	To ngin sdang da ka lamphrang sha ki variables.
00:49	Bash variables ka ai ia ka storage ba shipor na ka bynta ki information.
00:55	Kine ki variables lah ban pyndonkam hapoh jong ka katba ka program ka dang don
01:01	Don ar jait ki variables: System variables,User defined variables .
01:07	System variables: Kine la shna bad pynbiang da ka Linux Bash Shell hi.
01:14	La batai lane define ia ki da ki dak heh.
01:17	Ki system variables ba ju pyndonkam barabor kidei
01:20	BASH_VERSION . HOSTNAME
01:23	HOME etc
01:25	To ngin plié ia ka terminal da kaba nion Ctrl, Alt bad T keys ha kajuh ka por na ka keyboard jong phi.
01:33	Mynta , type: set bad nion Enter.
01:38	Kane kan pyni ia baroh ki system variables.
01:42	Ha kawei pat ka rukom, phi lah ban type envlane printenv ban peit ia baroh ki system variables.
01:53	To ngan clear ia ka prompt.
01:55	Mynta , type: echo space hapoh double quotes dollar sign HOSTNAME
02:01	Mynta nion Enter.
02:04	Ka hostname jong ka system kan sa paw.
02:07	Mynta to ngin wad ia ka path ba pura jong ka homedirectory.

03:20	Sngewbha kynmaw ba kam dei ban don blank space hapdeng ka username, equal to sign bad sunita.
03:29	Mynta, nion Enter. Ban pyni ia ka value jongvariable username,
03:33	Type: echo space hapoh double quotes dollar sign username
03:40	Nion Enter.
03:42	Kane kan sa pyni sunita ha ka terminal jong phi
03:46	U value jong u variable lah ban unset
03:50	To ngin phai biang sha ki slides jong ngi.
03:52	unset- u value jong u variable lah ban unset da kaba pyndonkam ia ka unset command.
03:59	Ka syntax na ka bynta kane kadei - unset variablename
04:03	To ngin pyndonkam ia ka nuksa ba hashwa ha kaba username udei u variable jong ngi.
04:08	Phai biang sha ka Terminal. Mynta type: unset space username, nionEnter.
04:18	To ngin check. Type: echo space hapoh double quotes dollar sign username nion Enter.
04:28	Kan nym paw eiei ha ka terminal.
04:30	Kane ka mut ba u value jong variable username la dep weng.
