In Linux, ‘man’ pages are an essential resource for understanding the various commands available on your system. The ‘man’ command provides comprehensive details about a given command, including its syntax and the switches used. Essentially, ‘man’ formats and displays the on-line manual pages.<\/p>\n
This tutorial will guide you through the process of installing the ‘man’ command on a CentOS 5.7 server. This is a crucial step for any system administrator or webmaster, as it enables you to access valuable information about the commands you’ll be using on your server. For more information about different types of servers, you can visit our pages on Apache<\/a>, Nginx<\/a>, and LiteSpeed<\/a>.<\/p>\n To install the ‘man’ command on your CentOS 5.7 server, you will need to use the ‘yum’ package manager. The ‘yum’ command is used to install, update, and remove software packages in Linux distributions like CentOS. Here are the steps to install the ‘man’ command:<\/p>\n Open your terminal. This command tells ‘yum’ to install the ‘man’ package. The ‘-y’ option is used to automatically answer ‘yes’ to any prompts that may come up during the installation process.<\/p>\n After running this command, ‘yum’ will begin the installation process. It will resolve any dependencies that the ‘man’ package might have and install them as well. In this case, the dependencies are ‘groff’ and ‘bzip2’. ‘groff’ is a typesetting system that reads plain text mixed with formatting commands and produces formatted output, while ‘bzip2’ is a free and open-source file compression program.<\/p>\n Once the installation process is complete, you can verify the installation by running the ‘man’ command followed by ‘man’ again, like so:<\/p>\n This command will display the manual page for the ‘man’ command itself, confirming that the ‘man’ command has been successfully installed on your CentOS 5.7 server.<\/p>\n In conclusion, the ‘man’ command is a vital tool for any webmaster or system administrator working with Linux, particularly CentOS 5.7. It provides comprehensive details about the various commands available on your system, making it an invaluable resource for understanding and using these commands effectively. By following the steps outlined in this tutorial, you can easily install the ‘man’ command on your CentOS 5.7 server.<\/p>\n Whether you’re working with a dedicated server<\/a>, a VPS server<\/a>, cloud hosting<\/a>, or shared hosting<\/a>, having access to ‘man’ pages will undoubtedly enhance your ability to manage and troubleshoot your server effectively.<\/p>\n What is the ‘man’ command in Linux?<\/p>\n \n The ‘man’ command inLinux is used to display the user manual of any command that we can run on the terminal. It provides a detailed view of the command which includes NAME, SYNOPSIS, DESCRIPTION, OPTIONS, EXIT STATUS, RETURN VALUE, ERRORS, FILES, VERSIONS, EXAMPLES, AUTHORS and SEE ALSO.<\/span>\n <\/p>\n<\/li>\n What is the ‘yum’ command in CentOS?<\/p>\n \n The ‘yum’ command is a package manager that helps you to install, update, and remove software packages in CentOS and other Linux distributions. It automatically computes dependencies and figures out what things should occur to install packages.<\/span>\n <\/p>\n<\/li>\n What is the purpose of the ‘-y’ option in the ‘yum’ command?<\/p>\n \n The ‘-y’ option in the ‘yum’ command is used to automatically answer ‘yes’ to any prompts that come up during the installation process.

\r\n[root@CentOS57 ~]# man man\r\n<\/pre>\n
\r\nman(1) man(1)\r\n\r\n\r\n\r\nNAME\r\n man - format and display the on-line manual pages\r\n\r\nSYNOPSIS\r\n man [-acdfFhkKtwW] [--path] [-m system] [-p string] [-C config_file]\r\n [-M pathlist] [-P pager] [-B browser] [-H htmlpager] [-S section_list]\r\n [section] name ...\r\n\r\n\r\nDESCRIPTION\r\n man formats and displays the on-line manual pages. If you specify sec-\r\n tion, man only looks in that section of the manual. name is normally\r\n the name of the manual page, which is typically the name of a command,\r\n function, or file. However, if name contains a slash (\/) then man\r\n interprets it as a file specification, so that you can do man .\/foo.5\r\n or even man \/cd\/foo\/bar.1.gz.\r\n\r\n See below for a description of where man looks for the manual page\r\n files.\r\n\r\n\r\nOPTIONS\r\n -C config_file\r\n Specify the configuration file to use; the default is\r\n \/etc\/man.config. (See man.config(5).)\r\n\r\n -M path\r\n Specify the list of directories to search for man pages. Sepa-\r\n rate the directories with colons. An empty list is the same as\r\n not specifying -M at all. See SEARCH PATH FOR MANUAL PAGES.\r\n\r\n -P pager\r\n Specify which pager to use. This option overrides the MANPAGER\r\n environment variable, which in turn overrides the PAGER vari-\r\n able. By default, man uses \/usr\/bin\/less -is.\r\n\r\n -B Specify which browser to use on HTML files. This option over-\r\n rides the BROWSER environment variable. By default, man uses\r\n \/usr\/bin\/less-is,\r\n\r\n -H Specify a command that renders HTML files as text. This option\r\n overrides the HTMLPAGER environment variable. By default, man\r\n uses \/bin\/cat,\r\n\r\n -S section_list\r\n List is a colon separated list of manual sections to search.\r\n This option overrides the MANSECT environment variable.\r\n\r\n -a By default, man will exit after displaying the first manual page\r\n it finds. Using this option forces man to display all the man-\r\n ual pages that match name, not just the first.\r\n\r\n -c Reformat the source man page, even when an up-to-date cat page\r\n exists. This can be meaningful if the cat page was formatted\r\n for a screen with a different number of columns, or if the pre-\r\n formatted page is corrupted.\r\n\r\n -d Don\u00e2t actually display the man pages, but do print gobs of\r\n debugging information.\r\n\r\n -D Both display and print debugging info.\r\n\r\n -f Equivalent to whatis.\r\n\r\n -F or --preformat\r\n Format only - do not display.\r\n\r\n -h Print a help message and exit.\r\n\r\n -k Equivalent to apropos.\r\n\r\n -K Search for the specified string in *all* man pages. Warning:\r\n this is probably very slow! It helps to specify a section.\r\n (Just to give a rough idea, on my machine this takes about a\r\n minute per 500 man pages.)\r\n\r\n -m system\r\n Specify an alternate set of man pages to search based on the\r\n system name given.\r\n\r\n -p string\r\n Specify the sequence of preprocessors to run before nroff or\r\n troff. Not all installations will have a full set of preproces-\r\n sors. Some of the preprocessors and the letters used to desig-\r\n nate them are: eqn (e), grap (g), pic (p), tbl (t), vgrind (v),\r\n refer (r). This option overrides the MANROFFSEQ environment\r\n variable.\r\n\r\n -t Use \/usr\/bin\/groff -Tps -mandoc to format the manual page, pass-\r\n ing the output to stdout. The default output format of\r\n \/usr\/bin\/groff -Tps -mandoc is Postscript, refer to the manual\r\n page of \/usr\/bin\/groff -Tps -mandoc for ways to pick an alter-\r\n nate format.\r\n\r\n Depending on the selected format and the availability of printing\r\n devices, the output may need to be passed through some filter or\r\n another before being printed.\r\n\r\n -w or --path\r\n Don\u00e2t actually display the man pages, but do print the loca-\r\n tion(s) of the files that would be formatted or displayed. If no\r\n argument is given: display (on stdout) the list of directories\r\n that is searched by man for man pages. If manpath is a link to\r\n man, then \"manpath\" is equivalent to \"man --path\".\r\n\r\n -W Like -w, but print file names one per line, without additional\r\n information. This is useful in shell commands like man -aW man\r\n | xargs ls -l\r\n<\/pre>\n
