我怎样才能填补空白，然后继续这个序列？

Question

我的代码查看序列中使用的最后一个活动设备，然后继续它。如果序列中存在当前未使用的空白，我想填补它。如何将其构建到代码中？

脚本按顺序按预期工作。我不确定从哪里开始添加功能来填补空白。

输入：

bash script WABEL8499IPM 3

脚本：

 SRCFILE="~/Desktop/deviceinfo.csv"  
 LOGDIR="~/Desktop/"  
 LOGFILE="$LOGDIR/DeviceNames.csv"  

 # base name, such as "WABEL8499IPM"
 device_name=$1
 # quantity, such as "2"
 quantityNum=$2

 # the largest in sequence, such as "WABEL8499IPM108"
 max_sequence_name=$(cat $SRCFILE | grep -o -e "$device_name[0-9]*" | sort --reverse | head -n 1)

 # extract the last 3digit number (such as "108") from max_sequence_name
  max_sequence_num=$(echo $max_sequence_name | rev | cut -c 1-3 | rev)

 # create a sequence of files starting from "WABEL8499IPM101"  if there is not any "WABEL8499IPM". 
 if [ -z "$max_sequence_name" ]; then    
    max_sequence_name=device_name
    max_sequence_num=100
 fi

 # Fill In Sequence If Any Spots are Available If 101, 102, 104, 
 # 105, 106, 107 and 108 are used I want to output 103 (to fill in), 
 # 109 and 110 (to continue sequence).
 # create new sequence_name
 # such as ["WABEL8499IPM109", "WABEL8499IPM110"]


 array_new_sequence_name=()
 for i in $(seq 1 $quantityNum); do
cnum=$((max_sequence_num + i))
array_new_sequence_name+=($(echo $device_name$cnum))
 done

 #CODE FOR CREATING OUTPUT FILE HERE
 #for fn in ${array_new_sequence_name[@]}; do touch $fn; done;

 # write log
 for sqn in ${array_new_sequence_name[@]};
 do
     echo $sqn >> $LOGFILE
 done

实际结果：

  #OUTPUT FROM WABEL8499IPM, 3
  #IF WABEL8499IPM101,102,104,105 ARE USED THEN OUTPUT IS THIS: 
  WABEL8499IPM106
  WABEL8499IPM107
  WABEL8499IPM108

期望/预期结果：

  #OUTPUT FROM WABEL8499IPM, 3
  #IF WABEL8499IPM101,102,104,105 ARE USED THEN OUTPUT IS THIS: 
  WABEL8499IPM103
  WABEL8499IPM106
  WABEL8499IPM107

基本上，在我当前的脚本中，我正在调用 API 以查看当前注册到 MDM 中的内容，然后查看序列中的最高数字并输出序列中的下一个数字。目标是在序列未完成的任何空白处填写序列。

这可能对你有用：

# create a test source file

$ cat > src_file <<-EOF
foo WABEL8499IPM102 bar WABEL8499IPM108 foo bar
WABEL8499IPM106
foo WABEL8499IPM104
foo bar
WABEL8499IPM105 WAbel8499IPM110 bar
EOF

# the actual code

$ cat script
#!/usr/bin/env bash

pre=$1
num=$2
f=src_file
s=101

((num==0)) && exit

grep -oP "$pre\K[0-9]+" "$f" | sort -n > tmp 

comm -13 tmp <(seq $s $((s+num+$(wc -l < tmp)))) | awk -v n=$num -v p="$pre" '{print p $0}NR>=n{exit}'

# execute the script

$ ./script WABEL8499IPM 5
WABEL8499IPM101
WABEL8499IPM103
WABEL8499IPM107
WABEL8499IPM109
WABEL8499IPM110
