我知道如何从文件中删除所有尾随空格,例如:
public class UploadFeeEntryItem implements java.io.Serializable {
private static final long serialVersionUID = -1209942461722257774L;
private Long uploadItemId;
//private Long uploadId;
private Long recordId;
private String errors;
private String sender;
private String customerId;
private String accountNumber;
private String routingNumber;
public UploadFeeEntry getUploadFile() {
return uploadFile;
}
public void setUploadFile(UploadFeeEntry uploadFile) {
this.uploadFile = uploadFile;
}
public Long getUploadItemId() {
return uploadItemId;
}
public void setUploadItemId(Long uploadItemId) {
this.uploadItemId = uploadItemId;
}
public Long getRecordId() {
return recordId;
}
public void setRecordId(Long recordId) {
this.recordId = recordId;
}
public String getErrors() {
return errors;
}
public void setErrors(String errors) {
this.errors = errors;
}
public String getSender() {
return sender;
}
public void setSender(String sender) {
this.sender = sender;
}
}
有没有办法,但不能只包含空格?
本着精神:
sed -i 's/ *$//' file
优选地,但不是必需的,具有sed。 任何Linux支持的解决方案都可以。

请确保之前出现其他字符:
sed -r 's/([^\s])\s+$/\1/' file
检查是否出现非空格字符(\s
),后跟任意数量的空格。如果是这样,只需打印此非空格字符,以便删除尾随空格。
使用cat -vet
查看标记:
$ cat -vet a
hello $
$
bye $
$ sed -r 's/([^\s])\s+$/\1/' a | cat -vet -
hello$
$
bye$
