From 3bef5d89b0c667e9fb7d1d9b44ba9b30d4d084e4 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 8 Aug 2017 16:46:39 +0200 Subject: ash: implement -d DELIM option for read The POSIX standard only requires the read builtin to handle -r: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html However, Bash introduced the option -d to override IFS for just one invocation, and it is quite useful. It is also super easy to implement in BusyBox' ash, so let's do that. The motivation: This option is used by Git's test suite. function old new delta .rodata 163505 163587 +82 shell_builtin_read 1244 1289 +45 readcmd 233 259 +26 builtin_read 258 263 +5 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 158/0) Total: 158 bytes Signed-off-by: Johannes Schindelin Signed-off-by: Denys Vlasenko --- shell/shell_common.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'shell/shell_common.h') diff --git a/shell/shell_common.h b/shell/shell_common.h index a82535c86..1b79bffca 100644 --- a/shell/shell_common.h +++ b/shell/shell_common.h @@ -42,7 +42,8 @@ shell_builtin_read(void FAST_FUNC (*setvar)(const char *name, const char *val), const char *opt_n, const char *opt_p, const char *opt_t, - const char *opt_u + const char *opt_u, + const char *opt_d ); int FAST_FUNC -- cgit v1.2.3
