pv (Pipe Viewer) can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.
Problem: using SWISH++ it is possible to search and sort PDF-files automatically
Solution: tools like pdftotext, find, scripts on Bash or Perl are required to perform quick and fast search within PDF and indexing PDF documents.
bzip2 and bunzip2 are file compression and decompression utilities. The bzip2 and bunzip2 utilities are newer than gzip and gunzip and are not as common yet, but they are rapidly gaining popularity. The bzip2 utility is capable of greater compression ratios than gzip. Therefore, a bzip2 file can be 10-20% smaller than a gzip version of the same file. Usually, files that have been compressed by bzip2 will have a .bz2 extension.
Doodle is a tool to quickly search the documents on a computer. Doodle builds an index using meta-data contained in the documents and allows fast searches on the resulting database. Doodle uses libextractor to support obtaining meta-data from various file-formats. The database used by doodle is a suffix tree, resulting in fast lookups.
auto-apt is a program that checks file access of programs running within auto-apt environments. If a program will access a file of uninstalled package, auto-apt will install the package containing the file, by using apt-get.
