How do I skip bash for loop if certain condition is satisfied under UNIX / Linux / BSD / OS X?
You can do early exit with break statement inside the for loop. You can exit from within a FOR loop using break using the following syntax:
for i in 1 2 3 4 5 6 8 9 10 do statements1 #Executed for all values of ''I'', up to a disaster-condition if any. statements2 if (disaster-condition) then break #Abandon the loop. fi statements3 # While good and, no disaster-condition. done
In this example, go through all conf file in /etc/ directory and break the loop if /etc/resolv.conf file, else loop will end when all files are checked and it will display not found message:
#!/bin/bash found=0 for i in /tmp/*.conf do if [ "$i" == "resolv.conf" ] then echo "resolv.conf found in /etc" found=1 break fi done if [ $found -eq 0 ] then echo "resolv.conf not found in /etc" fi
