02:28 Shon Enter.
02:30 Ngi lah ban iohi ia ka output da kaba plie out_(underscore)file.(dot)txt.
02:36 Type: cat space out_(underscore)file.(dot)txt.
02:42 Ngi lah ban iohi ia baroh ar ki error bad output.
02:48 Ka error na ka bynta ka directory /user lah record ha kane ka file.

04:11 Ngan copy ia kane ka lain jong u code bad ngan paste ia u hangne hapoh.
04:16 Nga kwah ba baroh ar ki khubor jong ka output bad error kin jah noh.
04:21 Te, ngan pynkylla ia kane ka bynta jong u code ba lah copy. > (greater than) kaba mut truncate lane write.
04:30 slash dev slash null kadei ka null file. 2>&1 (2 greater than ampersand 1)
04:37 Number “2” un sa redirect ia u standard error sha ka standard output, ba lah buhdak da u number “1”.
04:45 Mynta, nion ha Save. Save ia u code.
04:48 To ngin ia run ia ka file redirect.sh.
