eu quero substituir a saída para texto

Question

eu tenho abaixo do Código.

curl -X POST --data-urlencode 'payload={"channel": "#general", "username": "webhookbot", "text": "This is posted to #general and comes from a bot named webhookbot.", "icon_emoji": ":ghost:"}' https://hooks.slack.com/services/xxxxxxxxxxxxxxxxxxxx

este comando envia This is posted to #general and comes from a bot named webhookbot para Slack Channel , agora eu quero substituir Isto com a saída de

wc -l ips.txt | awk '{print $1}'

eu quero isso:

curl -X POST --data-urlencode 'payload={"channel": "#general", "username": "webhookbot", "text": "OUTPUT OF wc -l command , like number 154", "icon_emoji": ":ghost:"}' https://hooks.slack.com/services/xxxxxxxxxxxxxxxxxxxx

Como posso fazer isso?

Answer 2

Você deve poder usar backticks para expansão de comando:

curl -X POST --data-urlencode 'payload={"channel": "#general", "username": "webhookbot", "text": "'wc -l ips.txt | awk '{print $1}''", "icon_emoji": ":ghost:"}' https://hooks.slack.com/services/xxxxxxxxxxxxxxxxxxxx
