Couldn't find anything relevant in the archives or the documentation...
I have bash scripts that I want to run identically under Cygwin and
Linux, which sometimes require the scripts to detect the environment
and branch accordingly. There are numerous ways to do Cygwin detection,
but I was wondering what technique should work with the widest audience
and be most immune to future Cygwin developments.
FWIW, below are various techniques that work for *me* *today*, some of
which have obvious flaws.
if [ -f /usr/bin/cygwin1.dll ]; then
if [ $CYGWIN_ROOT ]; then
if [ $OSTYPE = cygwin ]; then
if [ $(uname -s | grep -c CYGWIN) -gt 0 ]; then
if [ $(grep -c cygwin <<< ${BASH_VERSINFO[5]}) -gt 0 ]; then
if is_cygwin; then # where is_cygwin is a locally-built C program
# that tests #ifdef __CYGWIN__
