i try to remove all the CRLF from the file

like this also tried tr -d "\n" and tr -d "\r" :

cat <<EOF >${TMPDIR}/csr.yaml
apiVersion: certificates.k8s.io/v1beta1
kind: CertificateSigningRequest
metadata:
 name: ${CSR_NAME}
spec:
 groups:
 — system:authenticated
 request: $(cat ${TMPDIR}/server.csr | base64 | sed -e 's/\r//g')
 usages:
 — digital signature
 — key encipherment
 — server auth
EOF

no matter what i do the end result file the part of the CERTIFICATE content is still contains the line break How can i remove it ?

Answer 1

Try:

cat -v file.csr | tr "^M" "\n" | tr -d "\n"

This will output the file with Windows file endings (-v) before using tr to replace the file endings (^M) with a new line and then delete the new lines (-d)
