This is controlled by the grep-save-buffers variable. The grep commands will offer to save buffers before The matching of the sequences isĬontrolled by grep-match-regexp, which can be customized toĪs with compilation commands (see Running Compilations under Emacs), while the grepĬommand runs, the mode line shows the running number of matches found Highlighting is provided via matching the ANSI escape Match will be highlighted, instead of the entire source line. When displaying a match in the source buffer, the exact Use of this feature by setting grep-highlight-matches to Markers around matches for the purpose of highlighting. Some grep programs accept a ‘ -color’ option to output special See Compilation Mode, for detailed description of commands and key YouĬan find the corresponding lines in the original files using M-g M-n, RET, and so forth, just like compilation errors. The output from grep goes in the *grep* buffer. Grep -nH -e foo *.el | grep bar | grep toto Your command need not simply run grep you can use any shellĬommand that produces output in the same format. (see Find Identifier References) in the buffer around point, and puts that into the Specify a prefix argument for M-x grep, it finds the identifier Regexp (usually in single-quotes to quote the shell’s specialĬharacters) followed by file names, which may use wildcards. Would give grep when running it normally: a grep-style To run grep, type M-x grep, then enter a command line Run zgrep and collect output in the *grep* buffer. Run grep via find, and collect output in the Run grep asynchronously under Emacs, listing matching lines in The output buffer uses Grep mode, which is a variant of Compilation The matches reported by grep as if they were errors. Visit the lines on which matches were found. With compilation errors, you can also run grep and then Just as you can run a compiler from Emacs and then visit the lines Next: Finding Syntax Errors On The Fly, Previous: Subshells for Compilation, Up: Compiling and Testing Programs 27.4 Searching with Grep under Emacs
