AWS iam 和 JQ 过滤角色的问题

Question

I'm trying to make a simple filtering script using AWS cli + jq (powershell or cmd in Windows).

aws iam list-roles | jq -c '.Roles[].RoleName | select(startswith ("blabla"))'

But getting this error:

jq: error: AD_/0 is not defined at <top-level>, line 1:
.Roles[].RoleName | select(startswith (AD_))
jq: 1 compile error

But using jqplay.org with same JSON everything works well. Any thoughts?

thanks!

aws iam list-roles | jq -c '.Roles[].RoleName | select(startswith ("blabla"))'

blabla_rolename_1

Answer 1

It looks like you might be missing a string after the startswith function. Try adding a string in quotes after startswith:

aws iam list-roles | jq -c '.Roles[].RoleName | select(startswith("blabla"))'

If you still get an error, you can try running the jq command without the -c flag to see the full output from jq , which might give you more information about the error.

aws iam list-roles | jq '.Roles[].RoleName | select(startswith("blabla"))

AFAIK Powershell does not support single quotes. Use double quotes and escaped double quotes instead:

aws iam list-roles | jq -c ".Roles[].RoleName | select(startswith (\"blabla\"))"
