The items in square brackets are optional. In my CMS, I am using it with those lines: The syntax for the grep command is as follows: grep OPTIONS PATTERN FILE. Here a function to check if a certain URL exist: SEE ALSO: about O_CREAT|O_EXCL (which is used with the 'x' modifier for fopen()) and problems with NFS Be sure to unlock and fclose() the file AFTER you're done with it, and not within the above function: NOTE: This method fails if the above function is not used for checking in all other scripts/processes as it doesn't actually lock the file.įIX: You could flock() the file to prevent that (although all other scripts similarly must check it with flock() then, see ). This step is purposely omitted from the function as to let scripts do calculations all the while being sure the file won't be "seized" by another process. IMPORTANT: The file will remain on the disk if it was successfully created and you must clean up after you, f.ex. ![]() The function will create a file if non-existent, following calls will fail because the file exists (in effect being a lock).
