zsh sleep assistance with loop
You are using the short form of the for loop, so that only the { curl ... } command forms the body of the loop; sleep 1 occurs after the for loop. Instead, ensure that the sleep command is in the body of the for loop with
while truedo for p in **/*.xml; do curl -X POST -H "Content-Type:application/xml" -d @"${p}" "https://url/postAPI" > "post_${p}" sleep 1 donedone(You could also put sleep 1 inside the {...} construct that forms the body of the short-form for loop, but I recommend avoiding that form except for quick, one-off loops in interactive shells.)
