我想創建一個腳本,如果我的文件存在然後執行刪除,然後從artifactory得到wget
。下面這段代碼運行出於某種原因不會刪除我的文件,並創建一個新的擴展名...例如cageo.crt.1
,.2
,.3
等如何在刪除前檢查文件是否存在?
當我嘗試調試它會顯示rm -f
但沒有文件名
#!/bin/bash -ex
#install Certificate
cd /deployment/scripts
# check if cert is already installed
file = cageo.crt
if [ -f $file ]; then
echo "File $file exists."
echo "Delete file and get latest"
rm -f $file
wget https://artifactory.geo.com/artifactory/cageo.crt
else
wget https://artifactory.geo.com/artifactory/cageo.crt
fi
這是我的輸出:
+ cd /deployment/scripts
+ file = cageo.crt
=: cannot open (No such file or directory)
cageo.crt: PEM certificate
+ '[' -f ']'
+ echo 'File exists.'
File exists.
+ echo 'Delete file and get latest'
Delete file and get latest
+ rm -f
+ wgethttps://artifactory.geo.com/artifactory/cageo.crt/cageo.crt

刪除'file','='和'cageo.crt'之間的空間。它應該讀取'file = cageo.crt' – iamauser
iamauser是正確的...還要確保你沒有使用rm的別名。使用完全合格的路徑...就像'/ bin/rm'。 –
您可以將wget命令移出if-then-else-fi塊 –
