Munyaya inotevera tichazotarisa zvimwe inoraira kushandisa karukureta kubva kuchiteshi kubva Kubuntu. Vazhinji vashandisi veGnu / Linux vanowanzo fanirwa kushandisa karukureta kubva kuchiteshi kanoverengeka pazuva kwechimwe chinangwa, saka zvinogara zvichinakidza kuziva dzimwe sarudzo.
Nhasi tinogona kuwana mirairo yakawanda inowanikwa nechinangwa ichi. Aya ma Calculator eiyo terminal anotibvumidza isu ita ese marudzi ekuverenga yakapusa, yesainzi kana yemari. Tichakwanisa zvakare kushandisa iyi mirairo mune Shell zvinyorwa zveanonyanya kuomarara math. Tevere isu tichaenda kunoona mamwe anonyanya kushandiswa.
Mirairo yekushandisa iyo Calculator mune iyo terminal
Bc raira
Bc inomirira Calculator yakakosha. Inotsigira yekumanikidza chaiyo manhamba nekudyidzana kuuraya kwezvirevo. Zvine kumwe kufanana mune syntax yemutauro weC programming.
Nokusingaperi, iwo wekuraira bc tichaiwana yakaiswa pane ese maGnu / Linux masisitimu. Kana iwe usingakwanise kuiwana yakaiswa pane yako Debian / Ubuntu system, unogona kushandisa unotevera kuraira kuisa bc nekuvhura terminal (Ctrl + Alt + T) uye kunyora mukati mayo:
sudo apt install bc
Shandisa iyo bc yekuraira
Tinogona shandisa iyo bc yekuraira kuti uite ese marudzi ekuverenga zvakananga kubva kumagumo (Ctrl + Alt + T) nekunyora mairi:
Kana tikashandisa iyo sarudzo -l iro rakajairwa masvomhu raibhurari iri kuzotsanangurwa:
bc -l
Calc raira
Calc Ndicho nyore Calculator izvo zvinotibvumidza isu kuti tiite ese marudzi ekuverenga pane yekuraira tambo. Kuiisa pane Debian / Ubuntu masisitimu, tinogona kushandisa unotevera kuraira mune iyo terminal (Ctrl + Alt + T) kuisa calc:
sudo apt install apcalc
Shandisa iyo calc raira
Tichakwanisa kushandisa iyo calc raira ku ita ese marudzi ese ekuverenga zvakananga kubva kune iyo terminal (Ctrl + Alt + T) uchishandisa iyo nzira yekudyidzanakunyora:
calc
Kana tichida kushandisa iyo isiri-yekudyidzana modhi, iwe unongofanirwa kunyora iwo kuraira uchiteverwa nekuvhiya kunofanira kuitwa:
calc 88/22
Expr raira
Uyu murairo ichapurinda kukosha kwekuvhiya kunofambidzana express pane zvakajairwa kuburitsa. Icho chikamu chemakomputa, saka hatidi kuisa iyo.
Shandisa iyo expr yekuraira
Isu tinoshandisa inotevera fomati kune ekutanga kuverenga.
Wedzera:
expr 5 + 5
Kubvisa:
expr 25 - 4
Kupatsanura:
expr 50 / 2
Gcalccmd raira
Gnome-Calculator ndiyo yepamutemo karukureta yeGNOME desktop nharaunda. Gcalccmd ndiyo koni yacho vhezheni yekushandisa Gnome Calculator.
Kuisa uyu murairo iwe unongofanirwa kuvhura terminal (Ctrl + Alt + T) uye nyora mairi:
sudo apt install gnome-calculator
Shandisa iyo gcalccmd raira
Mune inotevera skrini iwe unogona kuona mimwe mienzaniso yekushandisa:
gcalccmd
Mutemo weQalc
Iyo nyore kushandisa macalculator, asi inopa iyo simba uye kuita zvinhu zvakawanda Ivo anowanzo chengeterwa akaoma masvomhu mapakeji, pamwe neanobatsira maturusi ezuva nezuva zvinodiwa.
Zvimiro zvinosanganisira raibhurari hombe yezvinhu zvinogadziriswa, kuverenga kweyuniti uye shanduko, kuverenga kwekufananidzira (kusanganisira masanganiswa uye equations), zvine hungwaru kunyatso, masvomhu arithmetic, kuronga, uye iri nyore kushandisa interface (GTK + uye CLI).
Kune masisitimu eDebian / Ubuntu, isu tinokwanisa kushandisa qalc nekutaipa mune chinongedzo (Ctrl + Alt + T) unotevera kuraira:
sudo apt install qalc
Shandisa iyo qalc yekuraira
Mune inotevera skrini iwe unogona kuona mimwe mienzaniso kuti uwane zano shoma rekuti ungashandisa sei Calculator iyi:
qalc
Zvinogona kuva bvunza zvimwe nezve qalc pane peji rako GitHub.
Shell inoraira
Tichakwanisa shandisa mirairo yeShell senge echo, awk, nezvimwe. kuita kukarukureta kwekushanda. Semuenzaniso, kuti uite sarudzo iwe unofanirwa kungo nyora zvinotevera mune terminal (Ctrl + Alt + T):
echo $[ 34 * (12 + 27) ]
Mune ino kesi tichagona zvakare kushandisa akasiyana paunenge uchiita kuverenga
x=5 y=6 echo $[ $x + $y ]
Calculator hapana mubvunzo kuti ndechimwe chezvishandiso zvakakosha zvatinofanira kuva nazvo muhurongwa hwezuva nezuva. Neichi chikonzero, kana iwe uri maneja kana mushandisi anoshandisa iyo terminal mazuva ese, iyi mirairo iyo yatakaona kumusoro kumusoro inogona kubatsira.
