NAME
shtool-install - GNU shtool install(1) command SYNOPSIS
shtool install [-v|--verbose] [-t|--trace] [-d|--mkdir] [-c|--copy] [-C|--compare-copy] [-s|--strip] [-m|--mode mode] [-o|--owner owner] [-g|--group group] [-e|--exec sed-cmd] file [file ...] path DESCRIPTION
This command installs a one or more files to a given target path providing all important options of the BSD install(1) command. The trick is that the functionality is provided in a portable way. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -d, --mkdir To maximize BSD compatiblity, the BSD "shtool "install -d"" usage is internally mapped to the "shtool "mkdir -f -p -m 755"" command. -c, --copy Copy the file to the target path. Default is to move. -C, --compare-copy Same as -c except if the destination file already exists and is identical to the source file, no installation is done and the target remains untouched. -s, --strip This option strips program executables during the installation, see strip(1). Default is to install verbatim. -m, --mode mode The file mode applied to the target, see chmod(1). Setting mode to ""-"" skips this step and leaves the operating system default which is usually based on umask(1). Some file modes require superuser privileges to be set. Default is 0755. -o, --owner owner The file owner name or id applied to the target, see chown(1). This option requires superuser privileges to execute. Default is to skip this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory. -g, --group group The file group name or id applied to the target, see chgrp(1). This option requires superuser privileges to execute to the fullest extend, otherwise the choice of group is limited on most operating systems. Default is to skip this step and leave the operating system default which is usually based on the executing gid or the parent setgid directory. -e, --exec sed-cmd This option can be used one or multiple times to apply one or more sed(1) commands to the file contents during installation. EXAMPLE
# Makefile install: : shtool install -c -s -m 4755 foo $(bindir)/ shtool install -c -m 644 foo.man $(mandir)/man1/foo.1 shtool install -c -m 644 -e "s/@p@/$prefix/g" foo.conf $(etcdir)/ HISTORY
The GNU shtool install command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1997 for GNU shtool. It was prompted by portability issues in the installation procedures of OSSP libraries. SEE ALSO

NAME
shtool-rotate - GNU shtool log file rotation SYNOPSIS
shtool rotate [-v|--verbose] [-t|--trace] [-f|--force] [-n|--num-files count] [-s|--size size] [-c|--copy] [-r|--remove] [-a|--archive-dir dir] [-z|--compress [tool:]level] [-b|--background] [-d|--delay] [-p|--pad len] [-m|--mode mode] [-o|--owner owner] [-g|--group group] [-M|--migrate cmd] [-P|--prolog cmd] [-E|--epilog cmd] file [file ...] DESCRIPTION
This command rotates a logfile file by subsequently creating up to count (optionally compressed) archive files of it. Archive files are named "file.number[compress-suffix]" where number is the version number, 0 being the newest and "count-1" the oldest. A rotation step consists of the following steps 1. remove last archive file 2. shift archive file numbers 3. create archive file 0 from file 4. truncate/recreate file OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -f, --force Force silent creation of archive directory if it does not exists. Also skip missing intermediate logfiles in the rotation step. Default is to exit with error in both cases. FIXME -n, --num-files count Create count archive files. Default is 10. -s, --size size Only rotate if logfile exceeds size. The argument size can be specified also with the trailing units "K" (kilo), "M" (mega) or "G" (giga). The "prolog" and "epilog" are only executed if rotation actually takes place. -c, --copy Copy file to archive then truncate original. The default is to move file to archive. Unless an application reopens its logfile it will continue to write to the same file. In the default move case the application will write to the archive which it had previously opened as file. In the copy case the application will write to the original file. The drawback of the copy approach is that logfile entries are lost when they are written to file between the execution of the copy and the truncation operation. The drawback of the move approach is that the application needs to detect the move or must be triggered to reopen its log (i.e. through epilog). -r, --remove Removes file after rotation instead of providing a new empty file. -a, --archive-dir dir Specify the archive directory. Default is to create archives in the same directory as file is located. -z, --compress [tool:]level Enables compression of archive files with compression level level By default, the tools bzip2(1), gzip(1) and compress(1) are searched for in $PATH, but one also can override this by prefixing the compression level with one of the three particular tool names. -b, --background Enable background compression. -d, --delay Delays the compression of archive file number 0. This is useful if ``-c'' is not used, because an application might continue to write to archive file 0 through an already open file handle. -p, --pad len Enables padding with leading zeros in the number part of the filename "file.numbercompress-suffix". The default padding len is 1. This is interesting if more than 10 archive files are used, because it leads to still sorted directory listings. -m, --mode mode The file mode applied to the created files, see chmod(1). Setting mode to "-" skips this step and leaves the operating system default which is usually based on umask(1). Some file modes require superuser privileges to be set. Default is 0755. -o, --owner owner The file owner name or id applied to the created files, see chown(1). This option requires superuser privileges to execute. Default is to skip this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory. -g, --group group The file group name or id applied to the created files, see chgrp(1). This option requires superuser privileges to execute to the fullest extend, otherwise the choice of group is limited on most operating systems. Default is to skip this step and leave the operating system default which is usually based on the executing gid or the parent setgid directory. -M, --migrate cmd Execute a "migration" command just before the archive file number count-1 is removed from the filesystem. The specified cmd receives the archive filename as command line argument. -P, --prolog cmd Execute a "prolog" command before the rotation step. Useful in conjunction with -s. -E, --epilog cmd Execute a "epilog" command after the rotation step. Useful in conjunction with -s. EXAMPLE
# shell script shtool rotate -n10 -s1M -zbzip2:9 -d -r /var/log/ap.access.log shtool rotate -n5 -s128K -zbzip2:9 -d -r /var/log/ap.error.log apachectl graceful HISTORY
The GNU shtool rotate command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. Its development was prompted by the need to have a flexible logfile rotation facility in the OpenPKG project. SEE ALSO
