12 Awk is used as a pattern scanning and processing language. This is
13 the BusyBox implementation of that programming language.
15 config FEATURE_AWK_LIBM
16 bool "Enable math functions (requires libm)"
20 Enable math functions of the Awk programming language.
21 NOTE: This will require libm to be present for linking.
27 cmp is used to compare two files and returns the result
34 diff compares two files or directories and outputs the
35 differences between them in a form that can be given to
38 config FEATURE_DIFF_BINARY
39 bool "Enable checks for binary files"
43 This option enables support for checking for binary files
44 before a comparison is carried out.
46 config FEATURE_DIFF_DIR
47 bool "Enable directory support"
51 This option enables support for directory and subdirectory
54 config FEATURE_DIFF_MINIMAL
55 bool "Enable -d option to find smaller sets of changes"
59 Enabling this option allows the use of -d to make diff
60 try hard to find the smallest possible set of changes.
66 The original 1970's Unix text editor, from the days of teletypes.
67 Small, simple, evil. Part of SUSv3. If you're not already using
68 this, you don't need it.
74 Apply a unified diff formatted patch.
80 sed is used to perform text transformations on a file
81 or input from a pipeline.
87 'vi' is a text editor. More specifically, it is the One True
88 text editor <grin>. It does, however, have a rather steep
89 learning curve. If you are not already comfortable with 'vi'
90 you may wish to use something else.
92 config FEATURE_VI_MAX_LEN
93 int "Maximum screen width in vi"
98 Contrary to what you may think, this is not eating much.
99 Make it smaller than 4k only if you are very limited on memory.
101 config FEATURE_VI_8BIT
102 bool "Allow vi to display 8-bit chars (otherwise shows dots)"
106 If your terminal can display characters with high bit set,
107 you may want to enable this. Note: vi is not Unicode-capable.
108 If your terminal combines several 8-bit bytes into one character
109 (as in Unicode mode), this will not work properly.
111 config FEATURE_VI_COLON
112 bool "Enable \":\" colon commands (no \"ex\" mode)"
116 Enable a limited set of colon commands for vi. This does not
117 provide an "ex" mode.
119 config FEATURE_VI_YANKMARK
120 bool "Enable yank/put commands and mark cmds"
124 This will enable you to use yank and put, as well as mark in
127 config FEATURE_VI_SEARCH
128 bool "Enable search and replace cmds"
132 Select this if you wish to be able to do search and replace in
135 config FEATURE_VI_USE_SIGNALS
140 Selecting this option will make busybox vi signal aware. This will
141 make busybox vi support SIGWINCH to deal with Window Changes, catch
142 Ctrl-Z and Ctrl-C and alarms.
144 config FEATURE_VI_DOT_CMD
145 bool "Remember previous cmd and \".\" cmd"
149 Make busybox vi remember the last command and be able to repeat it.
151 config FEATURE_VI_READONLY
152 bool "Enable -R option and \"view\" mode"
156 Enable the read-only command line option, which allows the user to
157 open a file in read-only mode.
159 config FEATURE_VI_SETOPTS
160 bool "Enable set-able options, ai ic showmatch"
164 Enable the editor to set some (ai, ic, showmatch) options.
166 config FEATURE_VI_SET
167 bool "Support for :set"
173 config FEATURE_VI_WIN_RESIZE
174 bool "Handle window resize"
178 Make busybox vi behave nicely with terminals that get resized.
180 config FEATURE_VI_OPTIMIZE_CURSOR
181 bool "Optimize cursor movement"
185 This will make the cursor movement faster, but requires more memory
186 and it makes the applet a tiny bit larger.
188 config FEATURE_ALLOW_EXEC
189 bool "Allow vi and awk to execute shell commands"
193 Enables vi and awk features which allows user to execute
194 shell commands (using system() C call).
