DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN _v_i (visual) is a display-oriented text editor based on an underlying line editor _e_x(1). It is possible to use the command mode of _e_x from within _v_i and vice-versa. The visual commands are described on this manual page; how to set options (like automatically numbering lines and automatically starting a new output line when you type carriage return) and all _e_x line editor commands are described on the _e_x(1) reference page. When using _v_i, changes you make to the file are reflected in what you see on your terminal screen. The position of the cursor on the screen indicates the position within the file. IIIInnnnvvvvooooccccaaaattttiiiioooonnnn OOOOppppttttiiiioooonnnnssss The following invocation options are interpreted by _v_i (previously documented options are discussed in the NNNNOOOOTTTTEEEESSSS section at the end of this manual page): ----tttt _t_a_g Edit the file containing the _t_a_g and position the editor at its definition. ----rrrr _f_i_l_e Edit _f_i_l_e after an editor or system crash. (Recovers the version of _f_i_l_e that was in the buffer when the crash occurred.) ----LLLL List the name of all files saved as the result of an editor or system crash. ----wwww_n Set the default window size to _n. This is useful when using the editor over a slow speed line. ----RRRR RRRReeeeaaaaddddoooonnnnllllyyyy mode; the rrrreeeeaaaaddddoooonnnnllllyyyy flag is set, preventing accidental overwriting of the file. ----xxxx Encryption option; when used, _v_i simulates the XXXX command of _e_x and prompts the user for a key. This key is used to encrypt and decrypt text using the algorithm of _c_r_y_p_t(1). The XXXX command makes an educated guess to determine whether text read in is encrypted or not. The temporary buffer file is encrypted also, using a transformed version of the key typed in for the ----xxxx option. See _c_r_y_p_t(1). PPPPaaaaggggeeee 1111 vvvviiii((((1111)))) vvvviiii((((1111)))) ----CCCC Encryption option; same as the ----xxxx option, except that _v_i simulates the CCCC command of _e_x. The CCCC command is like the XXXX command of _e_x, except that all text read in is assumed to have been encrypted. ----cccc _c_o_m_m_a_n_d Begin editing by executing the specified editor _c_o_m_m_a_n_d (usually a search or positioning command). When used with -_t, the specified command is given after moving to the tag. The _f_i_l_e argument indicates one or more files to be edited. The _v_i_e_w invocation is the same as _v_i except that the rrrreeeeaaaaddddoooonnnnllllyyyy flag is set. The _v_e_d_i_t invocation is intended for beginners. It is the same as _v_i except that the rrrreeeeppppoooorrrrtttt flag is set to 1, the sssshhhhoooowwwwmmmmooooddddeeee and nnnnoooovvvviiiicccceeee flags are set, and mmmmaaaaggggiiiicccc is turned off. These defaults make it easier to learn how to use _v_i. vvvviiii MMMMooooddddeeeessss Command Normal and initial mode. Other modes return to command mode upon completion. EEEESSSSCCCC (escape) is used to cancel a partial command. Input Entered by setting any of the following options: aaaa AAAA iiii IIII oooo OOOO cccc CCCC ssss SSSS RRRR .... Arbitrary text can then be entered. Input mode is normally terminated with EEEESSSSCCCC character, or, abnormally, with an interrupt. Last line Reading input for :::: //// ???? or !!!!; terminate by typing a carriage return; an interrupt cancels termination. CCCCOOOOMMMMMMMMAAAANNNNDDDD SSSSUUUUMMMMMMMMAAAARRRRYYYY In the descriptions, CR stands for carriage return and EEEESSSSCCCC stands for the escape key.

FFFFIIIILLLLEEEESSSS /tmp default directory where temporary work files are placed; it can be changed using the ddddiiiirrrreeeeccccttttoooorrrryyyy option (see the _e_x sssseeeetttt command) /usr/share/lib/terminfo/?/* compiled terminal description database NNNNOOOOTTTTEEEESSSS Two options, although they continue to be supported, have been replaced in the documentation by options that follow the Command Syntax Standard (see _i_n_t_r_o(1)). A ----rrrr option that is not followed with an option-argument has been replaced by ----LLLL and ++++_c_o_m_m_a_n_d has been replaced by ----cccc _c_o_m_m_a_n_d. _v_i has a limit of 15,687,678 editable lines. Attempts to edit or create files larger than this limit cause _v_i to terminate with an appropriate error message. There is also a limit of 8192 bytes per line (languages with multibyte characters may therefore have fewer than 8192 characters per line; otherwise this is also the number of characters per line. Files with longer lines are not edittable (or even viewable) with this editor. Use of either _f_o_l_d(1) or _f_m_t(1) on the file (while changing the contents) can be used to avoid this limit. Several changes have been made and bugs fixed for XXXXPPPPGGGG4444 compliance. See the discussion about _p_a_r_a_g_r_a_p_h_s above, for one case. Additionally, the eeee (move to end of word) command had bugs skipping over single letter words, and skipped one to few words, when the current position was the last letter in a word. Formerly, the ordering of the ----cccc and ----tttt options was not defined, and the command was executed before moving to the tag. The order is now reversed. If a file is readonly, the !!!! override must now be used whenever you write the file, not just the first time. Tampering with entries in /_u_s_r/_l_i_b/_t_e_r_m_i_n_f_o/?/* (for example, changing or removing an entry) can affect programs such as that expect the entry to be present and correct. In particular, removing the "dumb" terminal may cause unexpected problems. The regular expression has been changed to XPG4 compliance, please see regcomp(5). SSSSEEEEEEEE AAAALLLLSSSSOOOO ctags(1), ed(1), edit(1), ex(1), regcomp(5), vi(1).
