如何将a.csv文件转换成a.txt格式

Question

csv file in excel and saved it as.txt and when I count the lines using wc -l there is one line less in the.txt format 17768 vs 17769. 1. Is this normal and if so which line is lost in the conversion? 2. What is the easiest way to make this conversion in bash? Thanks!

Answer 1

wc -l count records based on row delimiter ( \n ) most probably your last record do not have row delimiter.

For example echo commands add a new line at the end but printf won't.

Demo:

$echo -e "1\n2" | wc -l
2
$printf "1\n2" |  wc -l
1
$
$echo -e "1\n2" | od -c
0000000   1  \n   2  \n
0000004
$printf "1\n2" |  od -c
0000000   1  \n   2
0000003
$

Both printf and echo are print 2 records. But as we don't have row delimiter ( \n ) at the end of string wc is showing only 1 record

$echo -e "1\n2"
1
2
$printf "1\n2"
1
2$
