Eu tenho um endpoint REST do qual posso obter um token de acesso. Para obter o token de acesso (JSON web token, JWT) e exportar esse valor como uma variável de ambiente, eu faço o seguinte.
export ACCESS_TOKEN=$(curl -i -H 'Content-Type: application/json' -X POST -d @credentials.json http://localhost:8080/api/user/login)
Eu então faço eco desse token de volta ao console com echo $ACCESS_TOKEN e obtenho algo assim.

Observe que há um espaço antes do primeiro caractere. Eu não achei que isso fosse um problema, porque se eu exportasse o valor diretamente do console e, em seguida, fizesse um eco, o espaço ainda está lá.
export ACCESS_TOKEN=eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiI1MTBlMjRiYWZmZTY0NjMyOGRiNjg1N2ViMTdlZTE1NCIsImFkZHIiOiIwOjA6MDowOjA6MDowOjEiLCJzY2hlbWUiOiJodHRwIiwicG9ydCI6IjgwODAiLCJpYXQiOjE0NjgzNzg5NDV9.COGBYBrx3oQvA2kIiObBOYkEFIL2BODcrSivxWvhuLs-aLsrMGO2z2aCddpwS2yZUB88Q3GOIU8QklbnfRMprQ
Agora preciso usar esse token para testar meus pontos de extremidade REST e tentei algo como o seguinte.
curl -i \
-H 'x-access-token: '$ACCESS_TOKEN'' \
-X POST -d @mydata.json \
http://localhost:8080/api/data
No entanto, recebo a seguinte saída.

Se eu fizer diretamente export ACCESS_TOKEN=.... no shell seguido pelo mesmo comando curl , então tudo funciona.
Além disso, se eu colocar a exportação em um arquivo sh , seguido pelo comando curl acima, isso também funcionará.
#!/bin/bash
export ACCESS_TOKEN=eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiI1MTBlMjRiYWZmZTY0NjMyOGRiNjg1N2ViMTdlZTE1NCIsImFkZHIiOiIwOjA6MDowOjA6MDowOjEiLCJzY2hlbWUiOiJodHRwIiwicG9ydCI6IjgwODAiLCJpYXQiOjE0NjgzNzkwMjB9.lV6jSf9w5_AbsPrNcWcgQpS-DWQVxnH65u06BDGIyL-ST_gg4xXZ2KLAs-kbwckRB3OFy637G1op6PZ2tpHdUQ
Alguma ideia do que estou fazendo errado aqui?
