Travis-ci regex on travis_tag does not allow

Question

I have a travis segment where it checks the env variable cassadra_version.

if [ ! -z ${CASSANDRA_VERSION} ]; then ./setup-cassandra.sh; fi;

I would also like to run only if there are no tags called deploy.

I tried: if [ ! -z ${CASSANDRA_VERSION} ] && [ "${TRAVIS_TAG}" =~ '^((?!deploy).)*$' ]; then ./setup-cassandra.sh; fi; if [ ! -z ${CASSANDRA_VERSION} ] && [ "${TRAVIS_TAG}" =~ '^((?!deploy).)*$' ]; then ./setup-cassandra.sh; fi;

but it gives me a binary operator error

if [ [! -z ${CASSANDRA_VERSION} ] && [ "${TRAVIS_TAG}" =~ '^((?!deploy).)*$' ]]; then ./setup-cassandra.sh; fi;

also gives me an error

if [ [! -z ${CASSANDRA_VERSION} ] && [ ${TRAVIS_TAG} =~ '^((?!deploy).)*$' ]]; then ./setup-cassandra.sh; fi;

also.

then I also tried: if [$ {TRAVIS_TAG} = ~ '^ ((! deploy).) * $']; then. / setup -cassandra.sh; Fi `

it also gives me a binary operator.

Am I not performing regular expression correctly?

Answer 1

You are not far off, your main problem is that ~= not a universal test operator, but a specific bash . To use these extended bash test statements, you must use double brackets .

This will work:

if [ ! -z ${CASSANDRA_VERSION} ] && [[ "${TRAVIS_TAG}" =~ ^((?!deploy).)*$ ]]; then ./setup-cassandra.sh; fi;

Well, if your regex is correct;)
