我正面临一个问题，即我在文件中收到了一些特殊字符。下面的快照：
sed 's/^[^0-9]*//g' file.dat
我正在使用以下命令删除第一列中除数字以外的任何内容：

没有成功。该文件是在teradata的fastexport期间创建的，该过程在提取过程中会自行添加一些特殊字符。
关于命令的任何想法？
答案 0 :(得分：2)
如果要删除行中任何位置的任何非ASCII字符，可以使用tr。
tr -d '\000\200-\377' <file >file.new
答案 1 :(得分：1)
使用perl
SET DATABASE SQL SYNTAX ORA TRUE;
create table OWN_TABLE (
ID DECIMAL NOT NULL,
NAME VARCHAR(24) NOT NULL,
CAPACITY_SUPPLY_DATE DATE ,
);
仅匹配第一个逗号的数字，然后匹配其他所有内容。
答案 2 :(得分：0)
sed是大枪，
使用cut删除每行的开头：
cut -b 2- file.dat
2-是您要保留的字节范围，我不确定您有多少这样的奇怪字符，所以我会尝试1-，2-， 3-，4-，5-等
答案 3 :(得分：0)
看起来应删除的字符数在所有行中都是不变的。要从每行的开头删除固定数量的字符，只需执行
即可$ sed 's/^.....//' input >output
根据您的需要调整点数。
