CENTAUR UTILITIES ----------------- Version 1.21 2/13/2021 http:/www.centaur.pw <jon@centel.cc> ABOUT ----- A collection of 27 independent Linux shell utilities for various purposes. The 'dr' program requires the OpenSSL 'md5.h' header. The 'fd' program requires 'libcurl-devel'. COMPILING & INSTALLATION ------------------------ By default, a new directory, '/usr/utils', is created when installing the compiled utilities. The 'INSTALLDIR' variable in the Makefile may be changed; e.g. to '/usr/bin' to avoid the need to add a new entry to a user's PATH environment variable. To build all binaries: $ make To build an individual binary: $ make prog-name To move the compiled binaries to the installation directory (see above) and copy the included help files: $ make install To remove the object files generated by make: $ make clean To delete the installed binaries: $ make uninstall UTILITIES LIST -------------- a - Append block of text to files al - Append a line of text to a file color - Return an ANSI escape sequence for a color or stylization cop - Copy files ddir - Delete empty directories dl - Delete files dom - Get IP address of hostname dr - List directory contents dt - Display date and/or time fd - Download single files il - Insert a line into a file mkd - Create directories mkf - Create blank files mov - Move or rename files and directories msgcli - Simple telnet client which reads text from a message server msgsrv - Simple telnet server which outputs text upon connection ov - Write block of text to files, overwriting if they exist ovl - Write a line of text to a file, overwriting if it exists r - Display contents of files rdln - Read a specific line number from a file rl - Delete a specified line number from a file rn - Display contents of files with line numbers snd - Find and delete files with a specific name slasher - Corrupt and optionally delete files tell - Echo text to the screen wl - Write a line of text to a new file wt - Write block of text to new files utils-help - Display a quick reference table of utilities and their syntax NOTE: 'utils-help' is a shell script requiring Centaur Night version 1.3 to interpret the color codes contained within. If Night is not installed, use 'utils-help-nocolor' to display this table without color. The 'HELP' file is also copied to the installation directory. OPTIONS & PARAMETERS -------------------- <> - required parameter [] - optional parameter ... - any number of parameters, using wildcards or separated by a space Options must always be provided before other parameters when used. When specifying multiple options, they must be run together as one string, except when executing 'dt' or 'msgsrv'.
