You can restrict to exact column matches by preprocessing the pattern. DESCRIPTION: 48 serial software selectable, x86 CPU, supports Docker and Python, Global 4G LTE-A Pro cellular, 8 GB RAM, 64 GB SSD, embedded. Booted to my Linux Mint bootable USB, opens GParted, and it thrown a bunch of I/O errors at /dev/sda. Furthermore, this looks for patterns anywhere in the line for example, if the pattern file contains 1234, then lines such as 123456,345678,2348962312,1211138,1234 will match. After restart, the PC froze to the GIGABYTE logo. This outputs the matches in the order of the large file, and prints lines that match multiple patterns only once. This is usually done by telling grep to read patterns from a file: grep -F -f 300KFile 30MFile Setup Ubuntu Linux on Windows using wsl Getting Started with Linux Shell Commands using commands such as pwd, help, etc Listing files and folders in Linux.
You can pass multiple patterns to grep by putting them on separate lines. The key to performance is reading the huge file only once.
