fincore -- query in-core status of file pages SYNOPSIS
fincore [-qs] file ... DESCRIPTION
The fincore utility queries and displays in-core status of specified files. Note that the result can already be stale when being output due to other activities in the system. Thus it should be used only for advisory purposes. The fincore utility accepts the following options. -q The quiet mode. Outputs nothing unless the file has in-core pages. -s The summary mode. Only shows number of pages. EXAMPLES
The following example shows that /bin/cat and /bin/cp are fully cached in-core while the other executables are not in-core. numbers shown in the default output are page indexes in the file of each in-core pages. % fincore /bin/c* /bin/cat: 0 1 2 3 /bin/chio: /bin/chmod: /bin/cp: 0 1 2 3 4 5 /bin/cpio: /bin/csh: % fincore -s /bin/c* /bin/cat: 4 / 4 in-core pages (100.00%) /bin/chio: 0 / 5 in-core pages (0.00%) /bin/chmod: 0 / 3 in-core pages (0.00%) /bin/cp: 6 / 6 in-core pages (100.00%) /bin/cpio: 0 / 36 in-core pages (0.00%) /bin/csh: 0 / 41 in-core pages (0.00%) SEE ALSO
mincore(2) AUTHORS
The fincore utility is written by YAMAMOTO Takashi. CAVEATS
The concept of page cache is an implementation detail of the kernel. The fincore utility works using some assumptions on the current imple- mentation. Thus it might stop working in a future version of NetBSD. BUGS
The amount of CPU time the current implementation of fincore utility would take is roughly proportional to the file sizes. Ideally it should be proportional to the number of in-core pages. BSD

gzexe - compress executable files in place SYNOPSIS
gzexe [ name ... ] DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``gzexe /bin/cat'' it will create the following two files: -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~ /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that /bin/cat works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
gzip(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep). BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. GZEXE(1)
