By default, _a_e_g_r_e_p prints the matching lines. There is no need to name files on the command line, all the project and change source files are supplied automatically. All non-source files are ignored. Most of the _g_r_e_p(1) options are understood, in their long form. OOPPTTIIOONNSS The following options are understood: ----AAfftteerr--CCoonntteexxtt==_n_u_m_b_e_r Print _n_u_m_b_e_r lines of trailing context after matching lines. Places a line containing a group separator (--) between con- tiguous groups of matches. ----BBeeffoorree--CCoonntteexxtt==_n_u_m_b_e_r Print _n_u_m_b_e_r lines of trailing context before matching lines. Places a line containing a group separator (--) between con- tiguous groups of matches. ----BByyttee--OOffffsseett Print the 0-based byte offset within the input file before each line of output. --CChhaannggee _n_u_m_b_e_r This option may be used to specify a particular change within a project. See _a_e_g_i_s(1) for a complete description of this option. ----ccoolloorr Surround the matched (non-empty) strings, matching lines, con- text lines, file names, line numbers, byte offsets, and sepa- rators (for fields and groups of context lines) with escape sequences to display them in color on the terminal. ----CCoonntteexxtt==_n_u_m_b_e_r Print _n_u_m_b_e_r lines of output context. Places a line contain- ing a group separator (--) between contiguous groups of matches. ----CCoouunntt Suppress normal output; instead print a count of matching lines for each input file. With ----iinnvveerrtt--mmaattcchh option count non-matching lines. ----eexxtteennddeedd--rreeggeexxpp Interpret _p_a_t_t_e_r_n as an extended regular expression. ----FFiilleess--WWiitthh--MMaattcchheess Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match. ----FFiilleess--WWiitthhOOuutt--MMaattcchheess Suppress normal output; instead print the name of each input file from which no output would normally have been printed. The scanning will stop on the first match. ----ffiixxeedd--ssttrriinnggss Interpret _p_a_t_t_e_r_n as a list of fixed strings, separated by newlines, any of which is to be matched. --HHeellpp This option may be used to obtain more information about how to use the _a_e_g_r_e_p program. ----IIggnnoorree--CCaassee Ignore case distinctions in both the _p_a_t_t_e_r_n and the source files. ----IInnvveerrtt--MMaattcchh Invert the sense of matching, to select non-matching lines. ----IInniittiiaall--TTaabb Make sure that the first character of actual line content lies on a tab stop, so that the alignment of tabs looks normal. ----LLiinnee--BBuuffffeerreedd Use line buffering on output. ----LLiinnee--NNuummbbeerr Prefix each line of output with the 1-based line number within its input file. ----LLiinnee--RReeggeexxpp ----MMaaxxiimmuumm--CCoouunntt==_n_u_m_b_e_r Stop reading a file after _n_u_m_b_e_r matching lines. ----nnoo--mmeessssaaggeess Suppress error messages about nonexistent or unreadable files. ----OOnnllyy--MMaattcchhiinngg Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line. ----PPeerrll--RReeggeexxpp Interpret _p_a_t_t_e_r_n as a Perl regular expression. --PPrroojjeecctt _n_a_m_e This option may be used to select the project of interest. When no --PPrroojjeecctt option is specified, the _A_E_G_I_S___P_R_O_J_E_C_T envi- ronment variable is consulted. If that does not exist, the user's _$_H_O_M_E_/_._a_e_g_i_s_r_c file is examined for a default project field (see _a_e_u_c_o_n_f(5) for more information). If that does not exist, when the user is only working on changes within a sin- gle project, the project name defaults to that project. Oth- erwise, it is an error. ----UUnniixx--BByyttee--OOffffsseett Report Unix-style byte offsets. ----WWoorrdd--RReeggeexxpp Select only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word con- stituent character. Similarly, it must be either at the end of the line or followed by a non-word constituent character. Word-constituent characters are letters, digits, and the underscore. See also _a_e_g_i_s(1) for options common to all aegis commands. All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. You must use consecutive sequences of optional letters. All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important. For example: the arguments "-project", "-PROJ" and "-p" are all inter- preted to mean the --PPrroojjeecctt option. The argument "-prj" will not be understood, because consecutive optional characters were not supplied. Options and other command line arguments may be mixed arbitrarily on the command line, after the function selectors. The GNU long option names are understood. Since all option names for _a_e_g_r_e_p are long, this means ignoring the extra leading '-'. The "----_o_p_t_i_o_n==_v_a_l_u_e" convention is also understood. EEXXIITT SSTTAATTUUSS The _a_e_g_r_e_p command will exit with a status of 1 on any error. The _a_e_g_r_e_p command will only exit with a status of 0 if there are no errors.
