13 the BusyBox implementation of that programming language.
15 config FEATURE_AWK_MATH
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.

34 diff compares two files or directories and outputs the

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 line length in vi"

99 You may want to decrease this parameter if your target machine
100 benefits from smaller stack usage.
102 config FEATURE_VI_COLON
103 bool "Enable \":\" colon commands (no \"ex\" mode)"

126 config FEATURE_VI_USE_SIGNALS

133 Ctrl-Z and Ctrl-C and alarms.
135 config FEATURE_VI_DOT_CMD
136 bool "Remember previous cmd and \".\" cmd"
140 Make busybox vi remember the last command and be able to repeat it.
142 config FEATURE_VI_READONLY

165 bool "Handle window resize"
169 Make busybox vi behave nicely with terminals that get resized.
171 config FEATURE_VI_OPTIMIZE_CURSOR

180 bool "Allow vi and awk to execute shell commands"
184 Enables vi and awk features which allows user to execute
185 shell commands (using system() C call).
