Merge 2 txt files in a single tab delimited file in batch
提问by user767990
I'm stuck with this : I need to merge two text files in a single tab delimited text file, on a batch script. ex :
我对此很困惑：我需要在批处理脚本上将两个文本文件合并到一个制表符分隔的文本文件中。前任 ：
file1:
文件 1：
qwer
tyui
asdf
file2:
文件2：
1345
6876
8796
file3:
文件 3：
qwer 1345
tyui 6876
asdf 8796
All I need in fact, is a equivalent to Unix command : paste -d "\t" file1 file2 > file3
事实上，我只需要一个等价于 Unix 命令的命令： paste -d "\t" file1 file2 > file3

The answer of walid2me is awesome, this is only a small mofication to show how to make it safe against characters like !^in the file 1.txt, the content of file 2.txtis safe, a it is read with teh set/psyntax.
walid2me 的答案很棒，这只是一个小小的修改，展示了如何使它对!^文件中的字符安全，文件1.txt的内容2.txt是安全的，它是用set/p语法读取的。
@echo off
set f1=1.txt
set f2=2.txt
set "sep= " % tab %
(
setlocal DisableDelayedExpansion
for /f "delims=" %%a in (%f1%) do (
set "f1_line=%%a"
setlocal EnableDelayedExpansion
set /p f2_line=
echo(!f1_line!!sep!!f2_line!
endlocal
)
endlocal
)<%f2%
pause
goto :eof
As you can see, I only move the expansion of %%ajust before the setlocal EnableDelayedExpansion
如您所见，我只%%a在setlocal EnableDelayedExpansion
There is still another small flaw, as set/pstrips trailing control characters, like single CR, LF and also TAB.
This affects only the file 2.txt.
还有另一个小缺陷，如set/p删除尾随控制字符，如单个 CR、LF 和 TAB。
这仅影响文件 2.txt。
In depth analysis about set /pare at New technic: set /p can read multiple lines from a file
在深入分析大约set /p是在新工艺：集/ p可以从文件中读取多行
