I would suggest to put the absolute that for password.txt in shell script.

For Eg: if the password.txt is present in /opt/atlassian/jira/password.txt then put $cat(/opt/atlassian/jira/password.txt) in shell script.

I tried that,for example if my password is password123 the cat command will show my password on resuly but at the end same thing no such file or directory

curl --insecure -u "username":password123 -X PUT --data '{"fields" : {"customfield_10301" : "value"} }' -H "Content:application/json" https://url/rest/api/2/issue/(issueid : No such file or directory
