+msgstr ""

+msgid ""
+"As I [keep moving][posix-awk-0] [towards POSIX][posix-awk-1], I'm on the "
+"process of migrating all my Bash scripts to POSIX sh."
+msgstr ""
+
+msgid ""
+"As I dropped `[[`, arrays and other Bashisms, I was left staring at the "
+"first line of every script, wondering what to do: what is the POSIX sh "
+"equivalent of `#!/usr/bin/env bash`? I already knew that POSIX says nothing "
+"about shebangs, and that the portable way to call a POSIX sh script is `sh "
+"script.sh`, but I didn't know what to do with that first line."
+msgstr ""
+
+msgid "What I had previously was:"
+msgstr ""
+
+msgid ""
+"#!/usr/bin/env bash\n"
+"set -Eeuo pipefail\n"
+"cd \"$(dirname \"${BASH_SOURCE[0]}\")\"\n"
+msgstr ""
+
+msgid ""
+"Obviously, the `$BASH_SOURCE` would be gone, and I would have to adapt some "
+"of my scripts to not rely on the script location. The `-E` and `-o pipefail`"
+" options were also gone, and would be replaced by nothing."
+msgstr ""
+
+msgid "I converted all of them to:"
+msgstr ""
+
+msgid "#!/bin/sh -eu\n"
+msgstr ""
+
+msgid ""
+"I moved the `-eu` options to the shebang line itself, striving for "
+"conciseness. But as I changed callers from `./script.sh` to `sh script.sh`, "
+"things started to fail. Some tests that should fail reported errors, but "
+"didn't return 1."
+msgstr ""
+
+msgid ""
+"My first reaction was to revert back to `./script.sh`, but the POSIX bug I "
+"caught is a strong strain, and when I went back to it, I figured that the "
+"callers were missing some flags. Specifically, `sh -eu script.sh`."
+msgstr ""
+
+msgid ""
+"Then it clicked: when running with `sh script.sh`, the shebang line with the"
+" sh options is ignored, as it is a comment!"
+msgstr ""
+
+msgid "Which means that the shebang most friendly with POSIX is:"
+msgstr ""
+
+msgid ""
+"#!/bin/sh\n"
+"set -eu\n"
+msgstr ""
+
+msgid ""
+"when running via `./script.sh`, if the system has an executable at "
+"`/bin/sh`, it will be used to run the script;"
+msgstr ""
+
+msgid ""
+"when running via `sh script.sh`, the sh options aren't ignored as "
+"previously."
