Bash脚本：没有这样的文件或目录

Question

So, i need to run this run.sh file and i could not with windows default CMD . So i installed Cygwin64 Terminal and it acctualy reads the file, but at the end of the reading, it spams an error:

$ /cygdrive/c/Python27/Scripts/./run.sh
Starting scraper
Scrape complete, checking movies with imdb
C:\python27\python.exe: can't open file 'check_imdb.py': [Errno 2] No such file or directory

Inside run.sh :

#!/bin/bash
echo "Starting scraper"
scrapy runspider cinema_scraper.py -t json --nolog -o - > "movies.json"
echo "Scrape complete, checking movies with imdb"
python check_imdb.py movies.json

check_imdb.py is inside run.sh folder.

Answer 1

The file is referenced inside the script as a relative path.

python check_imdb.py movies.json

Relative means that it does not specify the whole path (starting with /), and is interpreted relative to the current directory, which you can find out with :

pwd

A path starting with / is said to be absolute.

The important thing is to remember a script interprets paths relative to the current directory, not the directory where the script is located.

You could change to the directory of the script before running it, with :

cd /cygdrive/c/Python27/Scripts

But if you do that, then you will need to provide an absolute path on the command line to your movies.json file.

Better yet, modify the script to have an absolute path:

python /cygdrive/c/Python27/Scripts/check_imdb.py movies.json
