我想更改以下可以长达数千行的文本列表。
目标是将NET1更改为NET66，但仅在具有NET1的12条线路上，而不更改NET10、NET11、NET12、NET13或其中具有NET1###的任何线路。
我试着用
sed -i s/NET1/NET66/g list
但它改变了所有线路中都有NET1(NET10改为NET660(谢谢你的帮助。

使用awk:
awk '{sub(/NET1$/, "NET66", $1)}1' file > outfile
即删除第一个字段末尾的NET1，然后打印记录。
或使用sed:
sed -i 's/^([0-9]*)NET1([[:space:]])/1NET662/' file
^([0-9]*)NET1([[:space:]])只在行首的数字后面以及后面跟着空白字符时与NET1匹配。CCD_ 6和CCD_。
