10 ຄຳ ສັ່ງ Linux ທີ່ມີປະສິດຕິພາບທີ່ຮູ້ຈັກ ໜ້ອຍ - ພາກທີ IV

ສືບຕໍ່ຊຸດທີ່ຮູ້ຈັກຫນ້ອຍ, ບົດຂຽນທີສີ່ຂອງຊຸດນີ້ຈະຊ່ວຍໃຫ້ທ່ານຮູ້ ຄຳ ສັ່ງທີ່ມີປະໂຫຍດແລະມີພາບເຄື່ອນໄຫວບາງຢ່າງ. ໃນທີ່ນີ້ພວກເຮົາເຂົ້າໄປໃນກອງປະຊຸມພາກປະຕິບັດ, ໂດຍບໍ່ມີທິດສະດີຫຼາຍ.

    • ໃນບົດຂຽນທີສີ່ຂອງຊຸດນີ້ເຊິ່ງປະກອບມີ ຄຳ ສັ່ງ Linux ທີ່ບໍ່ຮູ້ຈັກ ໜ້ອຍ, ມີມູນຄ່າທີ່ຈະຮູ້. ທ່ານອາດຈະຮູ້ກ່ຽວກັບ ຄຳ ສັ່ງເຫຼົ່ານີ້ແລ້ວ, ແນ່ນອນວ່າທ່ານເປັນຜູ້ໃຊ້ Linux ທີ່ມີປະສົບການແລະມັກການ ສຳ ຫຼວດ.

    32. strace Command

    strace ແມ່ນເຄື່ອງມືແກ້ໄຂເຊິ່ງໄດ້ຖືກນໍາໃຊ້ຕົ້ນຕໍໃນການແກ້ໄຂບັນຫາຈຸດປະສົງໃນ Linux. ມັນອາດຈະບໍ່ຖືກຕິດຕັ້ງໂດຍຄ່າເລີ່ມຕົ້ນໃນລະບົບຂອງທ່ານແລະທ່ານອາດຈະຕ້ອງການໃຫ້ ເໝາະ ສົມກັບຊຸດທີ່ຕ້ອງການ.

    ຕິດຕາມການປະຕິບັດ ຄຳ ສັ່ງໂດຍໃຊ້ ຄຳ ສັ່ງສາຍ:
