我有3个文件。一种是食物和类别的列表：
food="rice"
product="cereal"
food="beans"
product="bean"
food="cake"
product="bakery"
food="lettuce"
product="leaves"
第二个是仅列出食物的列表：
food="rice"
food="beans"
food="cake"
food="lettuce"
在第三个文件中，我的行包含/ food文件的字符串（例如/ food =“ rice”），我需要用第一个文件中列出的相应产品替换这些字符串。为了简化：在文件3的文件2中找到字符串，并用文件3的文件一的下一行替换。 我以为可能是grep和sed的组合，但我不知道该怎么做... 第三个文件看起来像这样
>[food="rice"] [some other sutff] [calories=398]
Here is a recipe with rice
>[food="beans"] [some other sutff] [calories=250]
Here is a recipe with beans
>[food="cake"] [some other sutff] [calories=100]
Here is a recipe for cake
>[food="lettuce"] [some other sutff] [calories=02]
Why would you need a recipe for lettuce?

这是使用sed的解决方案：
sed -f <(sed 'N;s/\n/\//;s/^/s\//;s/$/\//' one) three
如果第一个文件的每一行实际上都以空格开头，则变为
sed -f <(sed 'N;s/ *//g;s/\n/\//;s/^/s\//;s/$/\//' one ) three

这是function getFolder() {
return Folder.selectDialog('Please select the folder to be imported:', Folder('~'));
}
function importFolderAsLayers(selectedFolder) {
// if a folder was selected continue with action, otherwise quit
var document;
var mm = 2.83464567; // Metric MM converter…
// Set the script to work with artboard rulers
app.coordinateSystem = CoordinateSystem.ARTBOARDCOORDINATESYSTEM;
if (selectedFolder) {
document = app.documents.add(
DocumentColorSpace.RGB,
width = 720*mm,
height = 720*mm,
);
document = app.activeDocument;
var firstImageLayer = true;
var newLayer;
var thisPlacedItem;
var posX=10;
var posY=30;
var count=0;
// create document list from files in selected folder
var imageList = selectedFolder.getFiles();
for (var i = 0; i < imageList.length; i++) {
if (imageList[i] instanceof File) {
var fileName = imageList[i].name.toLowerCase();
if( (fileName.indexOf(".svg") == -1) ) {
continue;
} else {
if( firstImageLayer ) {
newLayer = document.layers[0];
firstImageLayer = false;
} else {
newLayer = document.layers.add();
}
// Give the layer the name of the image file
newLayer.name = fileName.substring(0, fileName.indexOf(".") );
// Place the image on the artboard
newGroup = newLayer.groupItems.createFromFile( imageList[i] );
newGroup.position = [ posX , posY ];
}
}
posX += newGroup.width;
if(posX > (newGroup.width*16)) {
posX = 0;
posY -= newGroup.height;
}
}
if( firstImageLayer ) {
// alert("The action has been cancelled.");
// display error message if no supported documents were found in the designated folder
alert("Sorry, but the designated folder does not contain any recognized image formats.\n\nPlease choose another folder.");
document.close();
importFolderAsLayers(getFolder());
}
} else {
// alert("The action has been cancelled.");
// display error message if no supported documents were found in the designated folder
alert("Rerun the script and choose a folder with images.");
//importFolderAsLayers(getFolder());
}
}
// Start the script off
importFolderAsLayers( getFolder() );

sed/awk答案 2 :(得分：0)
我看不到file2的用途。
$ cat tst.awk
BEGIN { FS="[][]" }
NR==FNR {
gsub(/^[[:space:]]+|[[:space:]]+$/,"")
if (NR%2) { food = $0 }
else { map[food] = $0 }
next
}
{
sub(/\[[^][]+/,"["map[$2])
print
}
$ awk -f tst.awk file1 file3
