I noticed some uses of ${srcdir} in shell scripts.
That is almost always better written as $srcdir.
The patch below converts most such variable references.
Here are the few remaining candidates:
$ git grep -i -E '\$\{[a-zA-Z_0-9]+\}'|grep -v Makefile.in.in
configure.ac: JAR_INSTALL_DIR=\${prefix}/share/java
configure.ac: JNI_INSTALL_DIR=\${libdir}
debian/rules: for TEST in ${DEBIAN_SKIP_TEST}; do \
debian/rules:# mv $${mod} $$(dirname $${mod})/libguestfsmod.so; \
java/Makefile.am:libguestfs_jar_DATA = libguestfs-${VERSION}.jar
java/Makefile.am:libguestfs-${VERSION}.jar: $(libguestfs_jar_class_files)
perl/lib/Sys/Guestfs/Lib.pm: "-f", '${Package} ${Version} ${Architecture} ${Status}\n',
perl/typemap: croak (\"${Package}::$func_name(): called on a closed handle\");
perl/typemap: croak (\"${Package}::$func_name(): $var is not a blessed HV reference\");
tests/data/Makefile.am: echo "$${i}abcdefghijklmnopqrstuvwxyz"; \
We could change all of those, too, except the ones in configure.ac
and Makefile.am, since they refer to Make variables. Even those
should be changed, but to use the preferred Makefile notation:
$(prefix), $(libdir), $(VERSION).

Subject: [PATCH libguestfs] maint: use $var notation rather than ${var} when
possible
The only case to avoid in a shell script is when the byte after the
"}" is word-constituent, and concatenating it would thus change the
name of the variable.
These changes were induced by running this command:
git grep -l -i -E '\$\{(srcdir|md)' \
|xargs perl -pi -e 's/\$\{(srcdir|md)\}($|\w)/\$$1$2/gi'
The "g" was needed because there was one line with two instances.
The "i" is to handle ${SRCDIR}. The ($|\w) ensures that concatenating
whatever follows the "}" won't change semantics.
* gobject/run-bindtests: Use "$srcdir", not "${srcdir}".
* haskell/run-bindtests: Likewise.
* java/run-bindtests: Likewise.
* ocaml/run-bindtests: Likewise.
* perl/run-bindtests: Likewise.
* python/run-bindtests: Likewise.
* ruby/run-bindtests: Likewise.
* tests/guests/guest-aux/make-debian-img.sh: Likewise, but $SRCDIR.
* tests/guests/guest-aux/make-ubuntu-img.sh: Likewise.
* tests/guests/guest-aux/make-windows-img.sh: Likewise.
* tests/md/test-mdadm.sh: Likewise, but $md.
