Subject: t3419-*.sh: Fix arithmetic expansion syntax error
X-Git-Tag: v1.7.4-rc0~3^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=00f66f0e4913110e19972a71a150a7b9d1bfd02f;p=git.git

t3419-*.sh: Fix arithmetic expansion syntax error

Some shells, for example dash versions older than 0.5.4, need to
spell a variable reference as '$N' rather than 'N' in an arithmetic
expansion. In order to avoid the syntax error, we change the
offending variable reference from 'i' to '$i' in function scramble.

There is nothing bash specific to this test script (and we shouldn't
have any bash dependent test).  Fix its shebang line.
