我正在處理一個非常簡單的腳本,但由於某些原因它的一部分似乎異步運行。Bash腳本不會等待,直到命令正確執行
singlePartDevice() {

# Create single partition
parted -s "$1" mklabel msdos
# Find size of disk
v_disk=$(parted -s "$1" print|awk '/^Disk/ {print $3}'|sed 's/[Mm][Bb]//')
parted -s "$1" mkpart primary ext3 4096 ${v_disk}
parted -s "$1" set 1 raid on
return 0
}
singlePartDevice "/dev/sdc"
singlePartDevice "/dev/sdd"
#/dev/sdc1 exists but /dev/sdd1 does not exist
sleep 5s
#/dev/sdc1 exists AND /dev/sdd1 does also exist
正如您在睡眠之前所看到的,腳本只是部分完成了工作。如何讓我的腳本等到分手完成其工作後才能成功?
