linux 运行shell脚本 Error: could not open "input.txt" for reading.
本帖最后由 Dawnstar 于 2019-11-13 09:04 编辑linux系统中我想运行一个shell脚本，脚本如下：
cd receptor
for f in *.pdb
do
$path/pythonsh $adtpy/prepare_receptor4.py -r $f -o "$f"qt
done
cd ..
$path/pythonsh $adtpy/prepare_ligand4.py -l ligand.pdb -o ligand.pdbqt
for c in receptor/*.pdbqt; do
b=`basename $c .pdbqt`
echo Processing receptor $b
mkdir -p Docking/$b
vina --config /data/home/test/conf/conf$f.txt --receptor $c --out Docking/${b}/out.pdbqt --log Docking/${b}/log.txt
done
文件准备：
运行脚本的文件夹下包含：
conf—文件夹
receptor--文件夹
ligand.pdb--文件
vina.sh--脚本文件
脚本运行：
$ sh vina.sh #运行脚本
出现错误：

百度一下说是conf文件夹下conf*.txt 文件的文件格式错误，
$ vi conf*.txt
:set ff
fileformat=doc
:set ff=unix#修改文件格式
：wq #保存
$ sh vina.sh
仍然报错，错误内容没变。
想请各位大神指教，到底是什么地方出现了错误。
今天自己又一步步排查了一下，发现把conf文件夹下的文件放到当前目录下就可以正常运行，
即把代码第13行的路径去掉即可运行。
vina --config conf.txt --ligand $f --out Docking/${b}/out.pdbqt --log Docking/${b}/log.txt
虽然可以正常运行了，但是还是不知道为什么放在文件夹下就不行，我已经查看每一级目录都具有可执行权限。
希望有了解的大神可以帮忙解疑。
