循环遍历一个连续的数字列表,在python中留下给定的数字,我可以这样做:
list = [s2 for s2 in range(6)[1:] if s2 != s1]
for s1 in list:
print s1

其中list包含除s1之外的所有数字
我如何在bash中做同样的事情?
只是continue用来跳过这一步:
for s in {1..5} # note there is no need to use $(seq...)
do
[ "$s" -eq 3 ] && continue # if var is for example 3, jump to next loop
echo "$s"
done
