How can I open a file, skip first 2 lines and get the 50th character?
EXP 0 R:\000\un\111\e00\e00noLog\1006\bdry_arc.e00
ARC 2
1 1 0 0 0 0 7
i.e., I want to get the "7" in the third line, how can I do that?
thx!!
推荐答案
7是这一行的第70个字符，而不是第50个字符。
使用标准的unix工具做一些事情比重新发明更好：
head -3 bla |尾巴-1 | cut -b 50

The 7 is the 70th character on this line, not the 50th.
Some things are better done with standard unix tools than reinvented:
head -3 bla | tail -1 | cut -b 50
