如果从命令行调用与从脚本运行，Linux 上的 Wget 保存文件的方式不同

Question

I use wget to download a file to my server.

When I paste this in the terminal command line: wget 'https://www.example.com/export/komatsu/komatsu_export.php?pass=Kowa444m11008&date=month' -O /root/workingdir/KOWA_SampleResult_ZAF_ date +"%Y%m%d" .csv

it saves the file as KOWA_SampleResult_ZAF_20221215.csv

But when I paste the same line into a.sh file and run the file eg sh kowa_automate.sh

it saves the file as 'KOWA_SampleResult_ZAF_20221215.csv'$'\r'

Why the discrepancy with the extra symbols: ' '$'\r'

Andrew

I tried running the script bash kowa_automate.sh.

Answer 1

The issue was that Linux interprets Windows created text files differently. Windows new lines include CR LF, whereas Linux only uses LF. Hence the \r.

If in a text editor such as notepad++ on windows; you must use the EOL conversion to Unix.
