linux - How to count number of tabs in each line using shell script?

Question

I need to write a script to count the number of tabs in each line of a file and print the output to a text file (e.g., output.txt).

How do I do this?

Answer 1

awk '{print gsub(/\t/,"")}' inputfile > output.txt

Answer 2

如果您将\t其视为字段分隔符，则每行将少一个\t字段：

awk -F'\t' '{ print NF-1 }' input.txt > output.txt

Answer 3

sed 's/[^\t]//g' input.txt | awk '{ print length }' > output.txt

基于这个答案。

Answer 4

这将给出文件中的选项卡总数：

od -c infile | grep -o "\t" | wc -l > output.txt

这将逐行为您提供选项卡数量：

awk '{print gsub(/\t/,"")}' infile > output.txt
