bash scripts: use /usr/bin/env for bash shebangs
Not all systems / distros have a `/bin/bash`, and these scripts are
more difficult to run at development time.
For example, my system is NixOS which doesn't have a /bin/bash. This
is not a problem for NixOS building ZFS as a package: the build
environment automatically replaces these shebangs with corrected
paths.
The problem is much more annoying at development time: either the
scripts don't run, or I correct them for my local machine and deal with
a perpetually dirty work tree.
Before committing this patch I confirmed there are existing scripts
which use `/usr/bin/env` to locate bash, so I am thinking this is a
safe transformation.
There are a handful of other shebangs in this repository which don't
work on my system. This patch is useful on its own specifically for
`commitcheck.sh`, otherwise I can't validate my commits before
submission.
Here are the remaining shebangs which NixOS systems won't have:
1274 #!/bin/ksh -p
91 #!/bin/ksh
89 #! /bin/ksh -p
2 #!/bin/sed -f
1 #!/usr/bin/perl -w
1 #!/usr/bin/ksh
1 #!/bin/nawk -f
plus this which will create an invalid shebang in
`tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`:
echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh
I chose to leave those alone for now, and gauge the interest in this
much smaller patch first.
The fixes for these are easy enough by simply using `/usr/bin/env ksh`:
91 #!/bin/ksh
1 #!/usr/bin/ksh
The fix for the other set is much trickier. Quoting the GNU coreutils
manual:
Most operating systems (e.g. GNU/Linux, BSDs) treat all text after
the first space as a single argument. When using env in a script it
is thus not possible to specify multiple arguments.
and not all `env`'s support arguments.
Mine (GNU Coreutils 8.31) does, though this feature is new since
April 2018, GNU Coreutils 8.30:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2
and worse, requires the -S argument:
-S, --split-string=S process and split S into separate arguments;
used to pass multiple arguments on shebang
lines
Example:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr"
/nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory
/nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines
$ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr"
2
1
GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's
would be unhappy with the `-S`:
https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation
BusyBox v1.30.1 does not, and does not have a `-S`-like option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr"
env: can't execute 'sort -nr': No such file or directory
Toybox 0.8.1 also does not, and also does not have a `-S` option:
$ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr"
env: exec sort -nr: No such file or directory
---
At any rate, if this patch merges and the remaining ~1,500 are updated,
the much larger patch should probably include a checkstyle-like test
asserting all new shebangs use `/usr/bin/env`. I also don't mind
dealing with NixOS weirdness if the project would prefer that.
