使用bash创建具有增量版本的新目录

每增加一个函数:

#!/bin/bash

next() {
  local l="$1"
  local a="$2"
  local l1 l2 l3 a1 a2 a3

  IFS="." read l1 l2 l3 <<< "$l"
  IFS="." read a1 a2 a3 <<< "$a"
  
  echo "$(($l1+a1)).$(($l2+a2)).$(($l3+a3))"
}

last="1.0.1"
add="0.0.1"

new=$(next "$last" "$add")
echo "$new"

输出:

1.0.2

awk

next=`echo "$last" | awk -F. '{print $1"."$2"."($3+1)}'`

平淡的 bash

#!/bin/bash

cd manifests || exit
last=$(printf "%s\n" [0-9]*.*.*[0-9]/ | sort -Vr | head -n 1)
last=${last%?} # Remove the last character, that is, the '/'
[[ -d $last ]] && mkdir "${last%.*}.$(( ${last##*.} + 1))"

manifests .
