work stores compiled JSPs and other assets. => You only need to “clean” the webapp directories under it on the rare occasions when an update to a WebApp is not picked up. temp is used to store files created using the Java File API for creating temporary files. => You can “clean” it every time … Read more
Dir::Tmpname.create You could use Dir::Tmpname.create. It figures out what temporary directory to use (unless you pass it a directory). It’s a little ugly to use given that it expects a block: require ‘tmpdir’ # => true Dir::Tmpname.create([‘prefix-‘, ‘.ext’]) {} # => “/tmp/prefix-20190827-1-87n9iu.ext” Dir::Tmpname.create([‘prefix-‘, ‘.ext’], ‘/my/custom/directory’) {} # => “/my/custom/directory/prefix-20190827-1-11x2u0h.ext” The block is there for code … Read more
This is a problem that is pretty common: generating a relation on the fly without creating a table. SQL solutions for this problem are pretty awkward. One example using a derived table: SELECT n.id FROM (SELECT 2 AS id UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7) AS … Read more
The temporary directory is /data/local/tmp. I’ve seen some comments that claim you need to be rooted to access it but I’m not sure that’s true. Whilst it is true that you need root to freely access /data, this is not required for /data/local/tmp. I have verified this on Android 5.1.1.
Yes. This method works well: + (void)clearTmpDirectory { NSArray* tmpDirectory = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:NSTemporaryDirectory() error:NULL]; for (NSString *file in tmpDirectory) { [[NSFileManager defaultManager] removeItemAtPath:[NSString stringWithFormat:@”%@%@”, NSTemporaryDirectory(), file] error:NULL]; } }

Files uploaded through POST are deleted right after php script finishes its execution. According to php.net: “The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.”
#table refers to a local temporary table – visible to only the user who created it ##table refers to a global temporary table – visible to all users
According to the java.io.File Java Docs The default temporary-file directory is specified by the system property java.io.tmpdir. On UNIX systems the default value of this property is typically “/tmp” or “/var/tmp”; on Microsoft Windows systems it is typically “c:\temp”. A different value may be given to this system property when the Java virtual machine is … Read more
The current best practice is: docker system prune Note the output from this command prior to accepting the consequences: WARNING! This will remove: – all stopped containers – all networks not used by at least one container – all dangling images – all dangling build cache Are you sure you want to continue? [y/N] In … Read more
