cscope [options] files

Interactive utility for finding code fragments in one or more C, lex, or yacc source files. cscope builds a symbol cross-reference (named cscope.out by default) and then calls up a menu. The menu prompts the user to search for functions, macros, variables, preprocessor directives, etc. Type ? to list interactive commands. Subsequent calls to cscope rebuild the cross-reference if needed (i.e., if filenames or file contents have changed). Source filenames can be stored in a file cscope.files. This file can then be specified instead of files. Options -I, -p, and -T are also recognized when placed in cscope.files.



Build the symbol cross-reference only.


Ignore uppercase/lowercase differences in searches.


Create output in ASCII (don't compress data).


Don't update the cross-reference.


Don't show the CTRL-E prompt between files.

-f out

Name the cross-reference file out instead of cscope.out.

-I dir

Search for include files in dir before searching the default (/usr/include). cscope searches the current directory, then dir, then the default.

-i in

Check source files whose names are listed in in rather than in cscope.files.


Use with -n pat to do a single search.


Run in line mode; useful from within a screen editor.

-P path

Use with -d to prepend path to filenames in existing cross-reference. This lets you run cscope without changing to directory where cross-reference was built.

-p n

Show the last n parts of the filename path. Default is 1 (filename); use 0 to suppress the filename.

-s dir

Look for source files in directory dir instead of in current directory.


Match only the first eight characters of C symbols.


Ignore file timestamps (assume no files changed).


Build cross-reference unconditionally (assume all files changed).


Print the cscope version on first line of screen.

-n pat

Go to field n of input (starting at 0), then find pat.
