I made it more robust by using \001, which is legit POSIX AFAIK. E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01" failed with: sed: -e expression #1, char 55: unknown option to `s' Signed-off-by: Jeremie Francois (on alpha) <jeremie.francois@...il.com> Signed-off-by: Masahiro Yamada <masahiroy@...nel.org> Signed-off-by: Sasha Levin <sashal@...nel.org> --- scripts/config | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/scripts/config b/scripts/config index e0e39826dae90..eee5b7f3a092a 100755 --- a/scripts/config +++ b/scripts/config @@ -7,6 +7,9 @@ myname=${0##*/} # If no prefix forced, use the default CONFIG_ CONFIG_="${CONFIG_-CONFIG_}" +# We use an uncommon delimiter for sed substitutions +SED_DELIM=$(echo -en "\001") + usage() { cat >&2 <<EOL Manipulate options in a .config file from the command line. @@ -83,7 +86,7 @@ txt_subst() { local infile="$3" local tmpfile="$infile.swp" - sed -e "s:$before:$after:" "$infile" >"$tmpfile" + sed -e "s$SED_DELIM$before$SED_DELIM$after$SED_DELIM" "$infile" >"$tmpfile" # replace original file with the edited one mv "$tmpfile" "$infile" } -- 2.20.1
