如果按标签隔开，则无法识别单词(Cannot recognize word if spaced by tab)

我遇到问题，如果文本文件中的单词由制表符分隔，而不是空格，则程序无法读取每个单词。

例如，这里是文件。

part_Q.txt：

NWLR35MQ 649 HCDA93OW 526 abc 1 def 2 ghi 3 注意在“abc”和“1”之间，有一个标签，而不是空格。还要注意，在“NWLR35MQ”和“649”之间，没有标签，但都是空格。第二条线也是如此。

输出：

NWLR35MQ 649 HCDA93OW 526 def 2 ghi 3

但是，如果我用文件中的空格替换“abc”和“1”之间的tab，那么它会像下面那样正确输出，

预期产出：

NWLR35MQ 649 HCDA93OW 526 abc 1 def 2 ghi 3

它正确显示文件中的所有单词。如何显示所有单词而不管标签页或空格？它应该在两种情况下显示所有单词。看起来这个节目把tab当作一个角色。

以下是源代码：

#!/bin/sh tempCtr=0 realCtr=0 copyCtr=0 while IFS= read -r line || [[ -n $line ]]; do IFS=' ' tempCtr=0 for word in $line; do temp[$tempCtr]="$word" let "tempCtr++" done # if there are exactly 2 fields in each line, store ID and quantity if [ $tempCtr -eq 2 ] then part_Q[$realCtr]=${temp[$copyCtr]} let "realCtr++" let "copyCtr++" part_Q[$realCtr]=${temp[$copyCtr]} let "realCtr++" copyCtr=0 fi done < part_Q.txt for value in "${part_Q[@]}"; do echo $value done

I have problem on that the program cannot read each word if words in text file is spaced by tab, not space.

For example, here is file.

part_Q.txt:

NWLR35MQ 649 HCDA93OW 526 abc 1 def 2 ghi 3 note that between "abc" and "1", there is a tab, not space. Also note that between "NWLR35MQ" and "649", there is no tab but all are spaces. same for 2nd line as well.

Output:

NWLR35MQ 649 HCDA93OW 526 def 2 ghi 3

However, if I replace tab between "abc" and "1" by space in the file, then it outputs correctly like below,

Expected output:

NWLR35MQ 649 HCDA93OW 526 abc 1 def 2 ghi 3

It correctly display all words in file. How can I display all words regardless of tab or space? it should display all words in both cases. It seems that the program regards tab as a character.

Below is source code:

#!/bin/sh tempCtr=0 realCtr=0 copyCtr=0 while IFS= read -r line || [[ -n $line ]]; do IFS=' ' tempCtr=0 for word in $line; do temp[$tempCtr]="$word" let "tempCtr++" done # if there are exactly 2 fields in each line, store ID and quantity if [ $tempCtr -eq 2 ] then part_Q[$realCtr]=${temp[$copyCtr]} let "realCtr++" let "copyCtr++" part_Q[$realCtr]=${temp[$copyCtr]} let "realCtr++" copyCtr=0 fi done < part_Q.txt for value in "${part_Q[@]}"; do echo $value done
