问题描述
我有一个巨大的平面文件100K记录每一个横跨3000列。我需要删除的数据段菲起始位置300归档前定位500。这是数据的敏感部位需要被消灭之前，我可以存档。
我要寻找一个AWK或SED或任何类似的命令能为我做的伎俩。

下面我删除了89位和95之间的字符。
一个小小的改变，我还需要编写改变的内容相同的文件。
Here I removed the char between position 89 and 95.One small change, I also need to write the changed content to the same file.
下面是脚本我有这么远。
我通过循环的所有文件，将它们分为最大行20000的文件，然后在归档前去除位置的X和Y的特点。
Below is the script I have so far.I am looping through all files, dividing them into files of max rows 20000 and then removing the characters from position X and Y before archiving.
在 LS currentfilename -1 *。[标题] [XX] [标题]
做
回声$ currentfilename
tempfilename = $ {currentfilename %%。*}
AWK -v A =$ tempfilename'{文件名= A的部分的INT（（NR-1）/ 20000）名.txt;打印>>文件名}$ currentfilename
AWK'{打印SUBSTR（0,1,522 $）SUBSTR（$ 0953）>>文件名}$ currentfilename
MV $ currentfilename $ APP_ROOT /存档
做
for currentfilename in ls -1 *.[tT][xX][tT]doecho $currentfilenametempfilename=${currentfilename%%.*}awk -v A="$tempfilename" '{filename = A "Part" int((NR-1)/20000) ".txt"; print >> filename}' $currentfilenameawk '{print substr($0,1,522) substr($0,953) >> filename}' $currentfilenamemv $currentfilename $APP_ROOT/Archivedone
推荐答案
假设位置的意思是字符
awk '{print substr($0,1,299) substr($0,501)}' file
如果它不然后编辑你的问题，以添加一些RE preSENTATIVE样本输入和预期的输出（例如5行，每行6列，而不是几千上万列线的）。
If it doesn't then edit your question to add some REPRESENTATIVE sample input and expected output (e.g. 5 lines of 6 columns each, not thousands of lines of thousands of columns).
