Time | Narration |
00:01 | Paralok, ngi pdiangsngewbha iaphi sha ka spoken tutorial halor ka Basics of redirection. |
00:07 | Ha kane ka jinghikai, ngin ia pule shaphang: |
00:10 | Ka input bad ka output ha ka Bash |
00:12 | Redirection bad file descriptors |
00:15 | standard input standard output |
00:18 | standard error da ka jingiarap jong katto katne ki nuksa. |
00:22 | Ban bud ia kane ka jinghikai, phi dei ban don ia ki jingtip jong ka Shell Scripting ha ka BASH. |
00:28 | Lada phim don, te na ka bynta ki jinghikai kiba iadei, sngewbha leit sha ka website jong ngi kumba la pyni http://www.spoken-tutorial.org |
00:34 | Na ka bynta kane ka jinghikai, nga pyndonkam da ka: |
00:36 | Ubuntu Linux 12.04 Operating System bad |
00:40 | GNU BASH version 4.2 |
00:43 | Sngewbha kynmaw, ka GNU Bash version 4 lane kaba kham shajrong lah ai jingmut na ka bynta kane ka jinghikai. |
00:50 | Ha ka GNU/Linux ngi lah ban phah ia ka output sha ka file lane read ia ka input na ka file. |
00:58 | Man ka Shell command kidon la kijong ki inputs bad outputs. |
01:03 | Input bad output lah redirect da kaba pyndonkam ia ka notation ba kyrpang ba lah intepreted da ka Shell. |
01:11 | Ban pynkylla ia ka default path jong ka input lane output la khot ka redirection. |
01:18 | Ha ka GNU/Linux baroh kidei ki file, kynthup ia ka hardware. |
01:24 | Ki values kiba shait pynphai barabor kidei: |
01:27 | '0' na ka bynta input kata ka keyboard |
01:31 | '1' na ka bynta ka output kata ka screen |
01:34 | '2' na ka bynta ka error kata ka screen. |
01:38 | 0, 1, 2 kidei ki POSIX numbers bad la tip ruh kum ki file descriptors (FD). |
01:46 | U re-director u pyndonkam ia ki POSIX numbers ban iakren bad u nongpyndonkam lane bad kawei pat ka program. |
01:54 | Standard input: standard input kadei ka default input method. |
02:00 | La pyndonkam da baroh ki commands ban read ia ka input. |
02:04 | La pynithuh ia u da u zero (0). |
02:07 | Ba la tip ruh kum stdin (Standard input). |
02:13 | Ka default standard input kadei ka keyboard. |
02:17 | Less than symbol udei u input redirection symbol. |
02:22 | Ka syntax kadei- command space less than symbol space filename. |
02:30 | To ngan plie ia ka file kaba kyrteng ka redirection dot sh. |
02:34 | Nga lah type katto katne ki code ha kane ka file. |
02:37 | Kane kadei ka shebang line. |
02:41 | Type: sort space less than symbol space file dot txt. |
02:48 | Kane kadei ka nuksa jong ka input redirection. |
02:52 | Ia ka input la shim na ka file file dot txt. |
02:57 | sort command ka leh ia ka sorting jong ki numbers kiba don ha ka file dot txt. |
03:04 | Nion ha Save. |
03:06 | To ngin ia run ia ka file redirection dot sh. |
03:10 | Plie ia ka terminal da kaba pyndonkam Ctrl, Alt bad T keys ha kajuh kapor na ka keyboard jong phi. |
03:18 | Shwa ia kata, to ngin ia peit ia ki contents jong ka file dot txt. |
03:23 | Type: cat space file dot txt. |
03:27 | Shon Enter. |
03:30 | Phi lah ban iohi ia ka file kaba don ia ki series jong ki numbers. |
03:35 | Mynta type: chmod space plus x space redirection dot sh. |
03:43 | Shon Enter. |
03:45 | Type: dot slash redirection dot sh |
03:48 | Shon Enter. |
03:51 | Ngi lah ban iohi ia ka output ha ka terminal hadien ba ngi lah dep sort. |
03:56 | Ki numbers lah sort ha ka order kaba kiew. |
04:00 | Phai biang sha ka slides jong ngi. |
04:03 | Standard output: standard output lah pyndonkam da baroh ki commands ban pyni ia ka output. |
04:10 | Ka default output lah pyni ha ka screen. |
04:14 | La pynithuh ia u da u number one (1). |
04:17 | Ba la tip ruh kum u stdout (Standard output). |
04:23 | ( > )Greater than symbol udei u output redirection symbol. |
04:28 | Ka Syntax kadei command space greater than symbol space filename. |
04:35 | To ngan leit biang sha ka file jong ngi ka redirection dot sh. |
04:41 | Comment ia u lain ba ha shwa kata u sort. |
04:45 | Hapoh jong u, type ls space greater than symbol space ls underscore file.txt |
04:55 | Kane kadei ka nuksa jong ka output redirection. |
04:59 | Ka jingmih na u 'ls' yn sa buh ha ka ls_file dot txt . |
05:06 | Ka 'ls' command ka lis ia ka jingtip shaphang ki files ha kawei ka directory. |
05:14 | Mynta, save ia ka file bad leit sha ka terminal. |
05:19 | To ngan clear ia ka prompt. Nyngkong, to ngin type 'ls' bad ngin peit ia ka jingmih. |
05:28 | Mynta shon ia u up-arrow key lai sien. |
05:33 | Kynmaw ia ka command ba hashwa dot slash redirection dot sh. |
05:38 | Bad shon Enter. |
05:41 | Mynta to ngin ia check lada ka output ka wan ne em ha ka rukom badei. |
05:46 | Type: gedit space ls underscore file dot txt bad shon Enter. |
05:56 | Mynta ngi lah ban iohi ia ka output ha kane ka file. Te ka redirect jong ngi kalong kaba jop. |
06:03 | Phai biang sha ka slides jong ngi. |
06:06 | Standard error: standard error kadei ka default output error. |
06:12 | La pyndonkam ia ka ban thoh ia baroh ki jingbakla ha ka system. |
06:16 | La pynithuh ia u da u number two (2). |
06:20 | Kaba la tip ruh kum stderr (Standard error). |
06:25 | Ka jingmih na ka default standard error ka paw ha ka screen lane ha ka monitor. |
06:32 | Two greater than symbol (2>) kadei ka error redirection symbol. |
06:36 | Ka syntax kadei command space 2 greater than symbol space error dot txt. |
06:44 | To ngan phai biang sha ka file redirection dot sh. |
06:49 | Ngin ia comment ia ka lain ba hashwa. Kata ka 'ls'. |
06:54 | Hapoh jong u, type: rm space backslash tmp backslash 4815 dot txt space 2 greater than symbol space error dot txt. |
07:11 | Ka error output ka lah redirected sha kaerror dot txt file. |
07:17 | Mynta, nion ha Save bad phai sha ka terminal. |
07:22 | Ngin ia type ia ka command ban iohi nyngkong ia ka jingbakla. |
07:26 | Type: rm space back slash tmp back slash 4815 dot txt |
07:36 | Shon Enter. |
07:38 | Ka error kaba paw kadei ka- |
07:40 | rm: cannot remove slash tmp slash 4815 dot txt: No such file or directory. |
07:49 | Mynta ngin ia execute ia ka file jong ngi. |
07:53 | Shon ia u up-arrow key |
07:55 | Bad kynmaw ia ka command ba hashwa dot slash redirection dot sh. |
08:01 | Shon Enter. |
08:03 | Mynta to ngin ia check lada ka error ka lah redirect ne em. |
08:07 | Type: gedit space error dot txt bad shon Enter. |
08:15 | Mynta ngi lah ban iohi ia ka error kaba redirect sha ka file error dot txt |
08:22 | Da kane ngi lah poi sha kaba kut jong kane ka jinghikai. |
08:26 | To ngin ia batai kyllum. |
08:28 | Ha kane ka jinghikai, ngi lah pule shaphang: |
08:31 | Ka input bad ka output ha ka Bash |
08:35 | Redirection bad file descriptors |
08:38 | standard input da kaba pyndonkam da u '<' (less than) symbol |
08:42 | standard output da kaba pyndonkam da u '>' (greater than) symbol |
08:47 | standard error da kaba pyndonkam da u '2>' (2 greater than symbol). |
08:52 | Kum ka kam na ka bynta jong phi- |
08:54 | Thoh ia ka program ha kano kano ka language kum ka C, C++, Java |
08:59 | Bad redirect ia ka output lane error sha ka file kaba thymmai. |
09:04 | Lane, shna ia ka text file da ki katto katne ki contents kum ka kyrteng bad jaka sah jong phi. |
09:11 | Redirect ia ki contents sha ka file kaba thymmai. |
09:15 | Peit ia ka video kaba don ha ka link ba lah ai harum. |
09:19 | Ka kyllum lang ia ka Spoken-Tutorial project. |
09:23 | Lada phim don ia ka bandwidth kaba biang, phi lah ban shu download bad peit ia ka hadien. |
09:28 | Ka kynhun jong ka Spoken Tutorial project: |
09:30 | Ka pynlong ia ki workshops da kaba pyndonkam da ki spoken tutorials. |
09:34 | Ka ai certificates sha kito kiba pass ha ka online test. |
09:38 | Na ka bynta ki jingtip ba bun, sngewbha thoh sha ka contact@spoken-tutorial.org |
09:46 | Spoken Tutorial project kadei shi bynta jong ka Talk to a Teacher project. |
09:50 | La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, Sorkar India. |
09:58 | Kham bun ki jingtip halor kane ka mission kidon ha ka link ba lah ai harum. |
10:04 | Ia kane ka script la noh synniang da ka FOSSEE bad ka kynhun jong ka Spoken-Tutorial. |
10:10 | Ma nga i Meboreen na Shillong, nga pynkut ia kane. Khublei shibun. |
