Ngiyithola kanjani imigqa yokuqala eyi-100 yefayela ku-Linux?
Ukubheka imigqa embalwa yokuqala yefayela, thayipha igama lefayela lekhanda, lapho igama lefayela kuyigama lefayela ofuna ukulibuka, bese ucindezela . Ngokuzenzakalelayo, ikhanda likukhombisa imigqa yokuqala eyi-10 yefayela. Ungakushintsha lokhu ngokuthayipha igama lefayela elithi head -number, lapho inombolo iyinombolo yemigqa ofuna ukuyibona.
Uwuthola kanjani umugqa othize efayeleni eliku-Unix?
Bhala i-bash script ukuze uphrinte umugqa othile efayeleni
- awk : $>awk '{if(NR==LINE_NUMBER) phrinta $0}' file.txt.
- sed : $>sed -n LINE_NUMBERp file.txt.
- ikhanda : $>head -n LINE_NUMBER file.txt | umsila -n + LINE_NUMBER Nansi i-LINE_NUMBER, iyiphi inombolo yomugqa ofuna ukuyiphrinta. Izibonelo: Phrinta umugqa kusuka efayeleni elilodwa.
