Ukukhishwa kwimisebenzi oyenzayo eBash

Kwesinye isikhathi sidinga ukwenza umyalo, ngokwesibonelo ukushintsha izimvume zefolda nokuqukethwe kwayo, kepha-ke sifuna lolu shintsho LUNGASETSHENZISWA kufayela elithile, noma kufolda ethile ... noma ngabe ingaphakathi kwefolda engaphezulu kwayo. esisebenzisa umyalo.
