Esihlokweni esilandelayo sizobheka okunye iyala ukusebenzisa umshini wokubala ovela esigungwini kusuka ku-Ubuntu. Abasebenzisi abaningi be-Gnu / Linux imvamisa badinga ukusebenzisa umshini wokubala ovela esigungwini izikhathi eziningana ngosuku ngenhloso ethile, ngakho-ke kuyathakazelisa njalo ukwazi ezinye izinketho.
Namuhla singathola imiyalo eminingi etholakalayo ngale njongo. Lezi zibali ze-terminal zizosivumela yenza zonke izinhlobo zezibalo elula, yesayensi noma yezezimali. Sizokwazi futhi ukusebenzisa le miyalo kwizikripthi zeShell ukuthola izibalo eziyinkimbinkimbi. Ngokulandelayo sizobona okunye okusetshenziswe kakhulu.
Imiyalo yokusebenzisa isibali esibulalayo
Umyalo we-Bc
I-Bc imele i-calculator eyisisekelo. Isekela izinombolo zokunemba ngokungenasisekelo ngokwenza izitatimende ezisebenzisanayo. Ine okunye ukufana ku-syntax yolimi lohlelo lwe-C.
Ngokuzenzakalelayo, umyalo bc sizoyithola ifakiwe kuzo zonke izinhlelo ze-Gnu / Linux. Uma ungayitholi ifakiwe kusistimu yakho ye-Debian / Ubuntu, ungasebenzisa umyalo olandelayo ukufaka i-bc ngokuvula i-terminal (Ctrl + Alt + T) bese uthayipha kuyo:
sudo apt install bc
Sebenzisa umyalo we-bc
I-Podemos sebenzisa umyalo we-bc ukwenza zonke izinhlobo zokubala ngqo kusuka ku-terminal (Ctrl + Alt + T) ngokuthayipha kuyo:
Uma sisebenzisa i- inketho -l umtapo wolwazi ojwayelekile wezibalo uzochazwa:
bc -l
Umyalo weCalc
I-Calc Kuyinto a wokubala elula lokho kusivumela ukuthi senze zonke izinhlobo zokubala kulayini womyalo. Ukuyifaka ezinhlelweni ze-Debian / Ubuntu, singasebenzisa umyalo olandelayo ku-terminal (Ctrl + Alt + T) ukufaka i-calc:
sudo apt install apcalc
Sebenzisa umyalo we-calc
Sizokwazi ukusebenzisa umyalo we-calc ku- yenza zonke izinhlobo zezibalo ngqo kusuka esigungwini (Ctrl + Alt + T) usebenzisa i- imodi yokusebenzisana, ukubhala:
calc
Uma sikhetha ukusebenzisa i- imodi engasebenzelani, kufanele ubhale umyalo olandelwa umsebenzi okufanele wenziwe:
calc 88/22
Umyalo we-Expr
Lo myalo izophrinta inani lomsebenzi ohambisana nalokhu veza kokukhipha okujwayelekile. Kuyingxenye yama-coreutils, ngakho-ke asidingi ukuyifaka.
Sebenzisa umyalo we-expr
Sizosebenzisa ifomethi elandelayo yezibalo eziyisisekelo.
Ukwengeza:
expr 5 + 5
Ukususa:
expr 25 - 4
Ukuhlukanisa:
expr 50 / 2
Umyalo we-Gcalccmd
I-Gnome-calculator isibali sokubala esisemthethweni semvelo yedeskithophu ye-GNOME. IGcalccmd inguqulo yekhonsoli yokusetshenziswa I-Gnome Calculator.
Ukufaka lo myalo kufanele uvule ukuphela (Ctrl + Alt + T) bese ubhala kuwo:
sudo apt install gnome-calculator
Sebenzisa umyalo we-gcalccmd
Ku-skrini elandelayo ungabona ezinye izibonelo zokusetshenziswa:
gcalccmd
Umyalo we-Qalc
I-calculator ekulula ukuyisebenzisa, kepha inikeza i amandla nokuguquguquka Imvamisa zigcinelwa amaphakheji wezibalo eziyinkimbinkimbi, kanye namathuluzi awusizo ezidingo zansuku zonke.
Izici zifaka umtapo wolwazi omkhulu wemisebenzi eyenziwe ngokwezifiso, ukubalwa kwamayunithi nokuguqulwa, ukubalwa okungokomfanekiso (kufaka phakathi ukuhlanganiswa nokulingana), ukunemba kokuphikisana, i-interval arithmetic, itulo, kanye nokusebenziseka okulula ukusebenzisa (I-GTK + ne-CLI).
Kuzinhlelo ze-Debian / Ubuntu, sizokwazi ukusebenzisa i-qalc ngokuthayipha ku-terminal (Ctrl + Alt + T) umyalo olandelayo:
sudo apt install qalc
Sebenzisa umyalo we-qalc
Ku-skrini elandelayo ungabona ezinye izibonelo ukuthola umbono omncane wokuthi ungasisebenzisa kanjani lesi sibali:
qalc
Kungaba njalo thintana kabanzi nge-qalc ekhasini lakho GitHub.
Igobolondo liyala
Sizokwazi sebenzisa imiyalo yeShell njenge-echo, awk, njll. ukwenza ukubalwa kokusebenza. Isibonelo, ukwenza inketho kufanele uthayiphe okulandelayo ku-terminal (Ctrl + Alt + T):
echo $[ 34 * (12 + 27) ]
Kulokhu sizokwazi nokusebenzisa okuguquguqukayo lapho wenza izibalo:
x=5 y=6 echo $[ $x + $y ]
I-calculator ngokungangabazeki ingenye yamathuluzi abaluleke kakhulu okumele sibe nawo kunoma yiluphi uhlelo lwansuku zonke. Ngalesi sizathu, uma ungumlawuli noma umsebenzisi osebenzisa i-terminal nsuku zonke, le miyalo esiyibone ngaphezulu ngenhla ingasiza.
