truncate -s 10G foo
fallocate -l 5G bar
It needs to be stated that truncate on a file system supporting sparse files will create a sparse file and fallocate will not
entr (http://entrproject.org/) provides a more friendly interface to inotify (and also supports *BSD & Mac OS X).
It makes it very easy to specify multiple files to watch (limited only by ulimit -n), takes the hassle out of dealing with files being replaced, and requires less bash syntax:
$ find . -name '*.py' | entr ./myfile.py
rpm2cpio ./packagecloud-test-1.1-1.x86_64.rpm | cpio -idmv
An RPM package is simply a header structure on top of a CPIO archive. The package itself is comprised of four sections: a header with a leading identifier (magic number) that identifies the file as an RPM package, a signature to verify the integrity of the package, the header or ‘tagged’ data containing package information, version numbers, and copyright messaging, and the archive containing the actual program files.
In the example above, we use cpio with the -i flag to extract the files from the archive, -d to create the leading directories where needed, and -m to preserve the file modification times when creating files. The -v flag (verbose) is to list the files processed for the sake of this example.
The log file containing the information referenced will usually be the one named with the hostname on which Tomcat is running. On a simple server (e.g. development environment) this is localhost.<datestamp>.log
