我们有一个字符串如下：
**XX_EMAIL_FILES FCP_REQID=9614696 FCP_LOGIN="APPS/sup12" FCP_USERID=5667 FCP_USERNAME="SRI" FCP_PRINTER="noprint" FCP_SAVE_OUT=Y FCP_NUM_COPIES=1 "9614556_SUP12_XX_Workflow_Stuck_AP_Invoices.csv" "/tmp_mnt2/attachments" "[email protected]" "This is the subject for the mail" "PFA for the list of Invoices that are stuck in workflow."**
我们只需将以下字符串提取到变量中：
这是邮件的主题
同样，只需将以下字符串提取到其他变量中： PFA 用于显示工作流程中停滞的发票列表。
这些并不总是相同的。字符串可能会根据用户输入的内容而有所不同。
谁能帮我了解如何使用 UNIX 命令仅获取这些字符串
问候， 博米

如果您确定字段的数量和顺序以及其中的引号，那么您可以使用cut -d\"以下方式获取必填字段：
echo 'XX_EMAIL_FILES FCP_REQID=9614696 FCP_LOGIN="APPS/sup12" FCP_USERID=5667 FCP_USERNAME="SRI" FCP_PRINTER="noprint" FCP_SAVE_OUT=Y FCP_NUM_COPIES=1 "9614556_SUP12_XX_Workflow_Stuck_AP_Invoices.csv" "/tmp_mnt2/attachments" "[email protected]" "This is the subject for the mail" "PFA for the list of Invoices that are stuck in workflow."' \
| cut -f14 -d\"
This is the subject for the mail
echo 'XX_EMAIL_FILES FCP_REQID=9614696 FCP_LOGIN="APPS/sup12" FCP_USERID=5667 FCP_USERNAME="SRI" FCP_PRINTER="noprint" FCP_SAVE_OUT=Y FCP_NUM_COPIES=1 "9614556_SUP12_XX_Workflow_Stuck_AP_Invoices.csv" "/tmp_mnt2/attachments" "[email protected]" "This is the subject for the mail" "PFA for the list of Invoices that are stuck in workflow."' \
| cut -f16 -d\"
PFA for the list of Invoices that are stuck in workflow.
awk或者如果您需要获取最后两个字段，使用方法可能更好：
echo 'XX_EMAIL_FILES FCP_REQID=9614696 FCP_LOGIN="APPS/sup12" FCP_USERID=5667 FCP_USERNAME="SRI" FCP_PRINTER="noprint" FCP_SAVE_OUT=Y FCP_NUM_COPIES=1 "9614556_SUP12_XX_Workflow_Stuck_AP_Invoices.csv" "/tmp_mnt2/attachments" "[email protected]" "This is the subject for the mail" "PFA for the list of Invoices that are stuck in workflow."' \
| awk -F\" '{ print $(NF-3) }'
This is the subject for the mail
