Question

我试图使用Cygwin运行一个简单的awk命令。

我想运行一个文件并将每行放到一个名为与第一个字段相同的文件中，将第一个字段中具有相同值的行追加到相关文件中。

我正在运行此命令：

gawk -F , '{print>\$1}' ./filename.csv

我从命令获得的唯一输出是：＆＃34;访问被拒绝。＆＃34;

C:\projects>gawk -F , '{print>\$1}' ./filename.csv  
Access is denied.

这就是它的总体情况。

我查看了文件权限并允许了所有内容，但我似乎无法让它工作。

根据要求编辑额外信息：

C:\projects>gawk -F , '{print > \$1}' filename.csv
Access is denied.

C:\projects>$SHELL --version
'$SHELL' is not recognized as an internal or external command,
operable program or batch file.

C:\projects>gawk --version

我试过从Cygwin Shell运行，我现在收到此错误：

/cygdrive/c/projects/FileSplit
$ gawk -F , '{print > $1}' ./filename.csv
gawk: cmd. line:1: (FILENAME=./filename.csv FNR=1) fatal: expression for `>' redirection has null string value

在Cygwin Shell中运行它虽然我的第一个字段在某些行上是空白的，但我最终得到的命令是：

gawk -F , '{if(length($1)==0)print > "empty"; else print > $1}' ./filename.csv

Answer 1

摆脱反斜杠：

gawk -F , '{print > $1}' ./filename.csv

鉴于您现在已经添加到您的问题中 - 您正在从Windows CMD提示中运行gawk，而不是从cygwin运行。不要这样做，从cygwin终端窗口运行gawk，而不是执行All Programs -> Cygwin -> Cygwin64 Terminal之类的操作来启动运行bash shell的cygwin窗口。

在Cygwin gawk给予＆＃34;访问被拒绝＆＃34;错误
