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. |
02:07 | Lada kam iadei bad iahap hangne ruh bad u VARIABLE, ki command kiba don jingiadei bad u asterisk kin sa shah execute. |
02:14 | Kadei ka case condition kaba long hi namar u asterisk un iahap bad iadei bad baroh ki strings. |

02:32 | Nga lah type lypa ia ka program. Te, ngan plie ia ka file “case.sh”. |
02:38 | Ka program ka print ia ka khubor kaba maham lada ka disk space ka jan kot sha ka limit ba la buh. |
02:45 | Kane ka dei ka “shebang line.” |
02:47 | Ka jaka jong ka bash ka iapher ha kiwei ki jait Linux kum ki CentOS, RedHat bad kiwei kiwei. |
02:55 | Ka /bin/bash kaba la pyndonkam hashwa ka kdew beit ia ka binary file. |
03:01 | La pyndonkam ia ka “env” hangne, kaba batai thikna ia ka jaka ba ka “bash” kadon. |
03:07 | Kane ka shebang line ka iarap ia ka jingsuk ban pyndonkam jong ka script ha ka GNU/Linux system. |
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. |
04:04 | Lada ka jingiadei kadon, kan print “Everything is OK” |

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”. |
05:18 | Check ia ka khubor kaba la print ha ka machine jong phi. |
