mktemp or tempfile ( for creating temporary files that do not need to exist between reboots !).truncate -size 0 /tmp/new_filename.txt.As mentioned, anything that can perform open(), openat() and, create() syscalls will create a file. In most shells nowadays true or : is a built-in, so doing : > /tmp/new_file is going to be more efficient, although marginally compared to touch /tmp/new_file.īut of course it does not stop there. That means, if the filename does not exist - it will be created, and if it does - the data will be truncated (and therefore gone, so > should be used with care). The > operator specifically calls the openat() system call with O_WRONLY|O_CREAT|O_TRUNC flags. Note also that a filename - is treated specially, so if you do want to create a file that is named literally -, you'll have to enclose that into single or double quotes.īy contrast, > is a shell redirection operator for stdout stream. Its original purpose is to update the access and modification time of a file, however if the file does not exist - it will be created.
Most commonly new filename is created with something like this: That means if you call any command-line utility that does these system calls, you can create a new empty file. CNC Milling, CNC Turning, Laser Cutting to Surface Grinding you can order the combination that suits your requirements, with just one phone call to our friendly staff.In general, creating any regular 1 file on Linux involves open(2), openat(2), and creat(2) system calls (and specifically with O_CREAT flags). Often with machining a second operation is often required such as Heat treatment, Assembly, Anodizing, Painting, Chemical Blacking, Laser Cutting, Waterjet Cutting, by using our own machinery and approved suppliers all this can now be performed under the same roof at Helix, saving the purchaser many hours raising individual purchase orders for a single job.
