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

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.

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.”
