If you leave this disabled, your utilities will be especially primitive and will be unable to determine the current screen width. comment "Common options for df, du, ls" depends on DF || DU || LS config FEATURE_HUMAN_READABLE bool "Support for human readable output (example 13k, 23M, 235G)" default n depends on DF || DU || LS help Allow df, du, and ls to have human readable output. comment "Common options for md5sum, sha1sum" depends on MD5SUM || SHA1SUM config FEATURE_MD5_SHA1_SUM_CHECK bool "Enable -c, -s and -w options" default n depends on MD5SUM || SHA1SUM help Enabling the -c options allows files to be checked against pre-calculated hash values. -s and -w are useful options when verifying checksums. endmenu
