What's wrong with my script?

[PingPing]

Code: [Select]

THAT="INSTALL_NO_USR FALSE"
for THIS in $THAT; do
    sed -i 's/# CONFIG_$THIS is not set/CONFIG_$THIS=y/' .config-test
doneIt doesn't work, yet I can do:

sed -i 's/# CONFIG_INSTALL_NO_USR is not set/CONFIG_INSTALL_NO_USR=y/' .config-test
sed -i 's/# CONFIG_FALSE is not set/CONFIG_FALSE=y/' .config-test

which both work.

Different shell levels of escaping; single quote prevents any and all shell interpretation. Use double quotes to get variables expanded.

Thx Curaga.  I'm using ash (busybox's default).  Replacing the 's with "s fixed it.
