Time	Narration
00:01	Paralok baieid, ngi pdiangsngewbha ia phi sha ka “spoken tutorial” halor ka “Case statement” ha “Bash.”
00:07	Ha kane ka jinghikai, ngin ia pule ia : ka jingdonkam jong ka “case statement”, Syntax jong ka “case statement” bad ki nuksa.
00:17	Ban bud ia kane ka jinghikai, phi dei ban don ia ka jingtip halor ka “Shell” scripting.
00:23	Lada phim don, te na ka bynta ki jingtip ba iadei bad kane, sngewbha leit sha ka website jong ngi kumba la pyni.
00:29	Na ka bynta kane ka jinghikai, nga pyndonkam: Ubuntu Linux 12.04 Operating System bad ka GNU BASH version 4.1.10
00:39	Sngewbha kynmaw, ka “GNU Bash” version 4 lane kaba kham shajrong lah ai jingmut na ka bynta kane ka jinghikai.
00:47	Ka Bash shell kadon ar jait ki conditional statements- 'if' statement bad ka 'case' statement.
00:56	Ka “Case” statement lah ban pyndonkam bujli ha ka jaka jong ka “if-else” statement.
01:03	Ka “case” statement kalong kaba la shim nyngkong ynda don bun tylli ki item kiba dei ban jied.
01:09	La kham pyndonkam ia ka ha ka ban pyntreikam ia ki “menu”s ha ka script.
01:14	To ngin ia peit ia ka syntax. case space $(dollar) VARIABLE space in match_1 close round-bracket space commands bad ar tylli ki semicolon
01:27	match_n close round-bracket space commands bad ar tylli ki semicolon asterisk close round=bracket space command_to_execute_by_default bad ar tylli ki semicolon esac.
01:45	Ia u “VARIABLE” la pynianujor bad match_1.
01:48	Lada kam iadei bad iahap, ka leit noh sha ka kawei ka case kaba dei ka match_n.
01:54	Kan check lada iwei napdeng kine ki strings ki iadei bad iahap bad u VARIABLE.
02:01	Lada 'yes' te baroh ki commands haduh ki double semicolon (;;) kin sa shah execute.

03:16	df -(hyphen)h ka pyni ia ka disk space kaba la pyndonkam ha ka rukom ban suk ban pule ki briew.
03:22	Ka output ka lah iasnoh bad ka sort -rk5 kaba pynbeit ryntih ia ka column kaba san ha ka order kaba da dien.
03:31	Nangta ka output ka pass sha ka awk 'FNR == 2 {print $5}'
03:38	Kaba sei ia ka “field” kaba san jong ka lain kaba ar.
03:43	Da kumne, ka output ka la pass sha ka cut -(hyphen)d “% -(hyphen)f1” ban weng ia u % sign.
03:55	Kane kadei ka line ba nyngkong jong ka “case statement.”
03:59	Hangne, ngi pynianujor ia ka “space” hapdeng u 0 bad 69.

04:17	Lada ka jingiadei kadon, kan print “Clean out. There's a partition that is $(dollar)space % full.”
04:27	Hangne, ka ia nujor ia ka “space” bad u 99.
04:30	Lada ka jingiadei kadon, kan print “Hurry. There's a partition at $(Dollar) space %!”
04:39	Kane kadei ka “case” condition kaba long hi namar u asterisk un ia pyniadei bad baroh ki “strings”.
04:45	Bad kane kadei kaba kut jong ka “case statement.”
04:48	Mynta, leit sha ka “terminal” ban pynlong ia ka file executable.
04:52	Type: chmod plus x case dot sh
04:57	Type: dot slash case dot sh
05:02	"Everything is OK". Kynmaw ba ka output kan iapher katkum ha ka disk space jong ka system jong phi.
05:10	Ha ka machine jong nga, kumba ka lap ba kadon ka jingiadei hapdeng u 0 bad 69, kan print “Everything is OK”.
