Question

我想使用shell或任何脚本来修改myfolder中可用的所有txt文件，如下所示

 test = data(x, y);

带

test = data(z,x,y);  // by adding z

和：

 test.value(f1, "directory_1/directory_2/directory_3/file");

带

test.value(f1, "/directory_3/file"); // by removing directory_1/directory_2

Answer 1

在bash中使用sed：

for i in *.txt; do
  if [ -f $i ]; then
    sed -i 's!test = data(\s*x,\s*y)!test = data(z,x,y)!' "$i"
    sed -i 's!test.value(f1, "[^/]*/[^/]*\(/[^"]*\)");!test.value(f1, "\1");!' "$i"
  fi  
done

Answer 2

cd myfolder
for FILE in *txt ; do
    sed -i 's/test = data(x,\s*y);/test = data(z,x,y);/;/test.value(f1, "/s="[^/]*/[^/]*\(/[^/]*/[^/]*");\)$=\1=;' "$FILE"
done

如果您的sed不是GNU，请使用

cd myfolder
for FILE in *txt ; do
    sed 's/test = data(x, y);/test = data(z,x,y);/test.value(f1, "/s="[^/]*/[^/]*\(/[^/]*/[^/]*");\)$=\1=;' "$FILE" > "$FILE.tmp"
    mv "${FILE}.tmp" "$FILE"
done

用于更新一组txt文件的shell脚本
