sed replace using string containing backslashes

阅读更多关于 sed replace using string containing backslashes

问题 I need to replace text in a file with a Windows-style directory path containing backslash (REVERSE SOLIDUS) characters. I am already using an alternative expression delimiter. The backslashes appear to be treated as escape characters. How can I keep the backslashes in the output? $ echo DIR=foobar | sed -e "s#DIR=.*#$(cygpath -w $(pwd))#" C:gwin64homelit The desired output is: C:\cygwin64\home\lit 回答1: You'll have to escape metacharacters in sed replacement pattern. Fortunately, there are

Cygwin和MinGW有什么区别？

Windows batches in Cygwin with spaces in path and arguments

阅读更多关于 Windows batches in Cygwin with spaces in path and arguments

问题 Consider this dummy Windows batch script: echo %1 Supposed just to echo to the terminal its first argument. Assume its path in resp. Windows, Cygwin style is: c:\test\win.bat /cygdrive/c/test/win.bat From Cygwin bash: $ c:\test\win.bat "hello world" "hello world" So quotes correctly identify a single argument. But now let us introduce spaces in path: "c:\te st\win.bat" /cygdrive/c/te\ st/win.bat Then: $ /cygdrive/c/te\ st/win.bat "hello world" Gives: "C:\te" is not recognized as an internal
