grep 在 bash 脚本中失败，但在命令行上工作 [英] grep fails inside bash script but works on command line
本文介绍了grep 在 bash 脚本中失败，但在命令行上工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
The bash file:
#!/bin/bash
grep -l -r "products" Products/
gives output
: No such file or directory
When run directly from the terminal prompt, grep -l -r "products" Products/ gives the desired output, which is the list of files containing the word.
I checked using echo $SHELL that the shell is indeed bash so there should be no difference. What could be the reason? (Products/ directory contains around 3500 files).
Running on Ubuntu 12.04 LTS.
解决方案
Your script contains a CR at the end of the grep line. Use dos2unix to remove it.
