I have a script that is one script in a chain of others that sends an email.
At the start of the script I want to check if a file exists and continue only if it exists, otherwise just quit.
Here is the start of my script:
if [ ! -f /scripts/alert ]; then echo "File not found!" && exit 0 else continue fi However I keep getting a message saying:
line 10: continue: only meaningful in a `for', `while', or `until' loop Any pointers?

-f filename ( test -f filename ) returns true if file exists and is a regular file.
Using Bash Continue with a for Loop Use the continue statement inside a conditional if to control the flow of a for : #!/bin/bash for i in {1.. 10} do if [[ $i == '9' ]] then echo "Number $i!" continue fi echo "$i" done echo "Done!"
Check if Directory Exist The operators -d allows you to test whether a file is a directory or not. [ -d /etc/docker ] && echo "$FILE is a directory." You can also use the double brackets [[ instead of a single one [ .
Change it to this:
{ if [ ! -f /scripts/alert ]; then echo "File not found!" exit 0 fi } A conditional isn't a loop, and there's no place you need to jump to. Execution simply continues after the conditional anyway.
(I also removed the needless &&. Not that it should happen, but just in case the echo fails there's no reason not to exit.)
