Time	Narration
00:01	Paralok baieid, ngi pdiangsngewbha iaphi sha ka “spoken tutorial” halor ka “String bad file Attributes comparison " ha Bash.
00:10	Ha kane ka jinghikai, ngin ia pule ia ka:
00:13	String comparison bad File attributes comparison.
00:18	Ngin ia leh ia kane da kaba pyndonkam katto katne ki nuksa.
00:22	Na ka bynta kane ka jinghikai, nga pyndonkam da ka:
00:25	Ubuntu Linux 12.04 Operating System bad
00:30	Ka GNU BASH version 4.1.10
00:34	Sngewbha kynmaw, ka “GNU Bash” version “4” lane kaba kham shajrong la ai jingmut na ka bynta kane ka jinghikai.
00:42	To ngin sdang da ka lamphrang.
00:45	Kidon ar tylli ki rukom ban ia nujor ia ka “string” ha ka “Bash”.
00:49	1) Nyngkong: da kaba pyndonkam == (equal to equal to) operator
00:53	ban ia nujor ia ar tylli ki “equal strings”.
00:56	2) Ba ar: != (not equal to) operator
00:59	Ban ia nujor ia ar tylli ki “not equal strings”.
01:03	To ngin ia peit ia ka nuksa.
01:06	Nga don hangne ia ka program kaba suk kaba check ia ka “user ID”.
01:11	Plie ia ka file ha ka “editor” jong phi bad “save” ia ka kum ka “strcompare dot sh”.
01:19	Mynta type ia u code kumba la pyni hangne, ha ka “strcompare dot sh” file.
01:26	To ngan batai ia u “code”.
01:28	Kane kadei ka “shebang line.”
01:31	“whoami” command ka ai ia ka “username” jong u “user” ba mynta.
01:36	Ka “if” statement ka check ia ka “output” jong u variable “whoami” pyrshah ia ka “string “root””.
01:44	Ngi lah pyndonkam ia u “not-equal to” operator hangne ban ia nujor ia ki strings.
01:50	Lada u nongpyndonkam ba mynta um dei u “root user.” Te kan sa “echo” ia kane ka statement-
01:57	“You have no permission to run 'strcompare dot sh' as non-root user.”
02:05	Hangne, $0 (dollar zero) udei u zeroth argument uba dei hi u 'file-name'.
02:13	Lada u nongpyndonkam udei u “root user” kan sa echo - “Welcome root!”.
02:18	Nangta ngi don ia ka “exit” statement na ka bynta ka program.
02:23	Bad hangne da ka “fi” ngi pynkut ia ka “if statement.”
02:28	To ngin ia phai biang sha ki “slides” ban tip kham bun shaphang ka “exit statement.”
02:34	Man ka program ka pynphai ia ka “exit status”.
02:38	Ka command kaba jop ka pynphai ia u “0” (zero).
02:42	Ka command kaba don ka jingbakla kan sa pynphai ia u non-zero “value.”
02:47	Ka lah ban ai kum ka “error code”.
02:51	Ngi lah ban customize ia u value jong ka “exit statement” ba la pynphai.
02:56	Mynta, to ngin “execute” ia ka program.
02:58	Plie ia ka “terminal window” da kaba nion “CTRL+Alt” bad “T” keys ha kajuh kapor na ka keyboard jong phi.
03:08	Nyngkong, to ngin ia check ia u nongpyndonkam ba mynta jong ka system.
03:12	Type: whoami.
03:15	Nion “Enter.”
03:17	Kane kan sa “output” ia ka kyrteng jong u nongpyndonkam ba mynta.
03:21	Mynta ngin pynlong ia ka script jong ngi executable.
03:25	Type: chmod + x strcompare dot sh
03:32	Type: dot slash strcompare dot sh
03:37	Ka “output” kan pyni kum:
03:39	You have no permission to run dot slash strcompare dot sh as non-root user.
03:47	Mynta to ngin execute ia kajuh ka program kum “root user.”
03:52	Type: sudo dot slash strcompare dot sh
03:58	Kan sa pan ia u password.
04:01	Ai ia u password jong phi hangne.
04:04	Ka output kan pyni kum: “Welcome root!.”
04:08	Mynta, to ngin pule shaphang ka “file attributes” comparison.
04:13	Nga lah don lypa ia ka nuksa jong u code ba donkam.
04:17	Ha kane ka program, ngin ia check lada ka file ba la ai kadon ne em.
04:23	file1 kadei ka variable ha kaba ngi la save ia ka path jong ka file.
04:29	-(hyphen) f command kan check lada ka file kadon ne em.
04:33	Bad lada kadei ne em ka file kaba biang.
04:37	Lada ka condition kadei True, kan sa echo "File exists and is a normal file" .
04:44	Lymda kumta, kan sa echo "File does not exist" .
04:48	Phai biang sha ka terminal. To ngin execute ia ka file jong ngi.
04:53	Type: chmod plus x fileattrib dot sh
05:00	Type: dot slash fileattrib dot sh
05:05	Ka output kan pyni kum:
05:07	"File exists and is a normal file".
05:11	Mynta ngin ia check lada ka file ka thylli ne em
05:16	Hashwa ban execute ia ka program jong ngi, ngan shna ia ka file ba thylli kaba kyrteng kum ka empty dot sh.
05:24	Type: gedit empty dot sh ampersand sign.
05:31	Nion ha “Save”, khang ia ka file.
05:35	To ngin ia bujli - (hyphen) f attribute da u - (hyphen) s attribute.
05:41	Bujli ia ka kyrteng jong ka file ruh kumjuh.
05:45	Type empty dot sh .
05:47	Mynta, bujli ia ka “echo statement” ba nyngkong da ka:
05:51	“File exists and is not empty”
05:54	Bad ka “echo statement” ba ar da ka:
05:57	“File is empty”.
05:59	Nion ha “Save”.
06:01	Phai biang sha ka “terminal”.
06:03	To ngan clear ia ka “prompt”.
06:06	To ngan “execute”.
06:08	Type: dot slash fileattrib dot sh bad shon Enter.
06:13	Ka output kadei "File is empty".
06:17	Mynta, to ngin ia peit ia kawei pat ka file attribute kaban check ia ka “write permission” jong kano kano ka file.
06:24	Phai biang sha ka program jong ngi.
06:26	To ngin bujli ia ka - (hyphen) s attribute da ka - (hyphen) w.
06:32	Mynta bujli ia ka “echo statement” ba nyngkong da ka:
06:36	“User has write permission to this file”.
06:40	Bad ia ka “echo statement” ba ar da ka:
06:43	“User doesn't have write permission to this file”.
06:47	Nion ha “Save”.
06:49	Ngan pyndonkam da kawei ka file na ka bynta kane ka nuksa.
06:53	Ngan jied ia ka file ka bym dei ka file kaba lah ban pule lane ka bym don ia ka “write permission”.
07:01	To ngan pynkylla ia ka “file path” sha ka
07:04	“slash etc slash mysql slash debian dot cnf”
07:10	Nion ha “Save”.
07:12	To ngin “execute” ia ka program jong ngi.
07:15	Nion ia u “up-arrow key”. Nion “Enter”.
07:19	Ngi iohi ba ka output ka paw kum:
07:21	"User doesn't have write permission to this file".
07:26	Mynta, to ngin ia peit ia kawei pat ka nuksa kaba shong nongrim ha ka “file attribute”s.
07:31	Ha kane ka nuksa, ngin ia check lada ka ‘file1’ kadei kaba kham thymmai ban ia ka ‘file2’.
07:38	To ngin ia peit ia ka program.
07:40	Kynmaw ba ka kyrteng jong ka file kadei ka fileattrib2 dot sh.
07:46	To ngin ia peit mynta ia u “code”.
07:48	Hangne ngi don ar tylli ki variables “file1” bad “file2”.
07:53	Ki ar tylli ki file lah dep shna lypa bad kidei kiba thylli.
07:58	Hangne, ngin ia check lada ka “file1” ka kham thymmai ban ia ka “file2.”
08:04	Lada ka “condition” kadei “True”, ngin print “file1 is newer than file2”.
08:09	Lymda kumta, "file2 is newer than file1".
08:14	Kane kadei kawei pat ka “if statement.”
08:16	Hangne ngi check lada ka “file1” ka kham rim ban ia ka “file2.”
08:21	Lada ka “condition” kadei “True”, ngi print “file1 is older than file2.”
08:27	Lymda kumta, ngin print “file2 is older than file1”.
08:32	Phai biang sha ka “terminal” jong ngi.
08:35	Nyngkong, ngin ia edit ia ka “empty1 dot sh” file
08:39	Ngan shu pyndap ia ka “echo statement” ha ka.
08:42	Type: echo within double quotes hiii after the double quotes greater than sign empty one dot sh. Nion Enter.
08:53	Mynta, to ngin ia pynlong ia ka “script” executable.
08:57	Type: chmod plus x fileattrib2 dot sh.
09:03	Mynta , type: dot slash fileattrib2 dot sh.
09:09	Ngi iohi ia ka output kum:
09:11	file1 is newer than file2
09:15	file2 is older than file1.
09:19	Mynta to ngin edit ia ka empty2 dot sh file.
09:23	Hangne ruh ngan pyndap ia ka echo statement.
09:27	Type: echo hapoh double quotes How are you hadien jong u quotes greater than sign (>)empty2 dot sh.
09:38	To ngan clear ia ka “prompt”.
09:41	Mynta to ngan “execute” ia ka “script” jong ngi sa shisien.
09:45	Nion ia u up-arrow key.
09:47	Leit sha ka dot slash fileattrib2 dot sh Shon Enter.
09:53	Mynta ka “output” ka paw kum:
09:55	"file2 is newer than file1"
09:59	Bad "file1 is older than file2".
10:03	Da kane ngi lah poi sha kaba kut jong kane ka jinghikai.
10:06	To ngan batai kyllum.
10:08	Ha kane ka jinghikai, ngi lah pule ia ka
10:11	String comparisonfile attributes
10:14	==(equal to equal to)
10:16	!= (not equal to)* -f (hyphen f)
10:18	-s (hyphen s)* -w (hyphen w)
10:21	-nt (hyphen nt) bad -ot (hyphen ot) attributes.
10:25	Kum ka kam na ka bynta jong phi- wad bniah shuh shuh sa kiwei kiwei ki attributes.
10:29	Kum ka nuksa: -r , -x and -o.
10:33	Peit ia ka video kaba don ha ka link ba la pyni harum.
10:36	Ka batai kyllum ia ka Spoken Tutorial project.
10:40	Lada phim don ia ka bandwidth kaba biang, phi lah ban shu download bad peit ia ka hadien.
10:45	Ka kynhun jong ka Spoken Tutorial:
10:47	Ka pynlong ia ki workshops da kaba pyndonkam da ki spoken tutorials.
