Question

我是linux和/或脚本的新手，所以请耐心等待。我想要一个可以获取Linux目录文件的脚本。在这里我尝试获取文件名。

for NAME in $(ls -1 *.wav /some/path | cut -d "/" -f3 | cut -d "-" -f1-5)

如果文件名包含-IN或-OUT，则它们将 sox -m ，之后 mv 到另一个目录，但如果是其他一些文件，那么它只是 mv

作为参考，文件名就像

1030-04-06-2015-1433414216.wav
  1030-04-06-2015-1433414318.wav
  1030-04-06-2015-1433414440.wav
  1043-21-05-2015-1432207256.wav
  1043-21-05-2015-1432207457.wav
  1046-20-05-2015-1432137944.wav
  1046-20-05-2015-1432138015.wav
  1046-20-05-2015-1432138704.wav
  1431709157.93900.0-in.wav
  1431709157.93900.0-out.wav
  1431709157.93900.1-in.wav
  1431709157.93900.1-out.wav
  1431710008.94059.0-in.wav
  1431710008.94059.0-out.wav
  1431710008.94059.1-in.wav
  1431710008.94059.1-out.wav
  1431710008.94059.1.wav
  1431710008.94059.2.wav
  1431713190.94698.2-in.wav
  1431713190.94698.2-out.wav
  1431713190.94698.2.wav
  1431721107.96010.0-in.wav
  1431721107.96010.0-out.wav
  1431721107.96010.1.wav

Answer 1

这是一种方法。

>cat test.sh
#!/bin/bash

destination="./DEST"

# Loop over every file
for file in "${@}" ; do
  # If it is "-in", then sox
  if [[ "${file}" =~ "-in" ]] || [[ "${file}" =~ "-out" ]] ; then
    printf "sox -m ${file}; "
  fi
  echo "mv ${file} ${destination}"
done

运行时，我得到以下输出。

如果要执行命令，只需将这些行剪切并粘贴到shell中，或修改bash脚本以执行这些命令而不是打印它们。

这应该有效：

#!/bin/bash
regex='(.*)(-out|-in)(.txt)'
for file in *.txt;do
# $file is the full path to the file
  if [[ $file =~ $regex ]];then
  #filename in this block contains -in or -out 
    filename="${file##*\/}"
    inorout="${BASH_REMATCH[2]}"
    extension="${BASH_REMATCH[3]}"
    filenamewithoutextension="${filename%.*}"
    filenamewithoutioroutorextension="${filenamewithoutextension/%$inorout/}"
    filenamewithoutiorout="${filenamewithoutioroutorextension}$extension"
    echo "$filename" "$inorout" "$extension" "$filenamewithoutextension" "$filenamewithoutiorout" "$filenamewithoutioroutorextension"
    #do something here sox-m mv or whatever
  else
  #filename in this block doesn't contain -in or -out
    echo "do something else"
  fi
done

<小时/> 说明：

"${file##*\/}"是从*/切割$file所留下的字符串，即基本名称（文件名）。

"${BASH_REMATCH[2]}"是由[[ $file =~ $regex ]]完成的模式匹配中的第二个捕获组，即-in或-out

"${BASH_REMATCH[3]}"是第三个被捕获的群体，即.wav。

"${filename%.*}"是从.*切换$file而不是.wav的文件名留下的字符串
