我有一个文件test.sh.在这里我的内容看起来像
Nas /mnt/enjayvol1/backup/test.sh lokesh
thinclient rsync /mnt/enjayvol1/esync/lokesh.sh lokesh
crm rsync -arz --update /mnt/enjayvol1/share/mehul mehul mehul123
我想检索匹配content / mnt
的字符串我想要输出线
/mnt/enjayvol1/backup/test.sh
/mnt/enjayvol1/esync/lokesh.sh
/mnt/enjayvol1/share/mehul
我试过了
grep -i "/mnt" test.sh | awk -F"mnt" '{print $2}'
但这不会给我准确的输出。请帮忙
答案 0 :(得分:2)
你能不能尝试一下awk方法,让我知道这是否对你有帮助。
awk -v RS=" " '$0 ~ /\/mnt/' Input_file
输出如下。
/mnt/enjayvol1/backup/test.sh
/mnt/enjayvol1/esync/lokesh.sh
/mnt/enjayvol1/share/mehul
说明:将记录分隔符作为空格,然后检查是否有任何行包含/ mnt字符串,如果是,则不提及任何操作,因此默认打印将会发生。因此它将打印那些在其中有/ mtn刺痛的行。

短 grep 方法(假设 / mnt ... 路径不包含空格):
<?php
include "db.php";
/* lat/lng data will be added to this array */
$locations=array();
$query = $db->query("SELECT * FROM ds_petroling_history");
while( $row = $query->fetch_assoc() ){
$nama_kabkot = $row['name'];
$longitude = $row['lng'];
$latitude = $row['lat'];
/* Each row is added as a new array */
$locations[]=array( 'name'=>$nama_kabkot, 'lat'=>$longitude, 'lng'=>$longitude );
}
/* Convert data to json */
$markers = json_encode($locations);
?>
<html>
<head>
</head>
<body>
<div><?php echo $markers ?></div>
<script type='text/javascript'>
<?php
echo "var markers=$markers;\n";
?>
function initMap() {
var latlng = new google.maps.LatLng(23.0117523,72.5226665);
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: false
};
var map = new google.maps.Map(document.getElementById("peta"),myOptions);
var infowindow = new google.maps.InfoWindow(), marker, lat, lng;
var json=JSON.parse( markers );
for( var o in json ){
lat = json[ o ].lat;
lng=json[ o ].lng;
name=json[ o ].name;
marker = new google.maps.Marker({
position: new google.maps.LatLng(lat,lng),
name:name,
map: map
});
google.maps.event.addListener( marker, 'click', function(e){
infowindow.setContent( this.name );
infowindow.open( map, this );
}.bind( marker ) );
}
}
</script>
<div id="peta" style="width: 100%; height: 660px;">
</div>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=yourkey&callback=initMap"

输出:
grep -o '\/mnt\/[^[:space:]]*' lokesh.sh
