  • To use this comment you'll have to create a file entitled 'ignorelist' where you put the file name or pattern of the files you want to ignore. I used it for my maven project which generates the child project files in each folder so I can import them into eclipse. By adding these project files to the ignore list ensure they won't appear each time I run 'svn status'. Show Sample Output

  • This executes faster than cygstart.exe I put this in a script and added it to my path: cat `which explore.sh` #!/bin/bash if [ $# -eq 0 ]; then explorer.exe $( cygpath `pwd` -w ) & else explorer.exe $( cygpath $1 -w ) & fi; Using the script you just type explore.sh file_or_executable Note: you can do this for any file that has an associated executable in the windows registry. This is quite handy if you want to open pictures or movies from xterm. Show Sample Output

    explorer $( cygpath "/path/to/file_or_exe" -w )

  • Remove blank lines from files, even if some of the lines have whitespace (spaces, tabs, etc.). Also creates a .bak copy of the original file. Works on Mac also. Thanks to those all those who left comments. Show Sample Output

  • Removes all unversioned files and folders from an svn repository. Also: svn status --no-ignore | grep ^I | awk '{print $2}' | xargs rm -rf will remove those files which svn status ignores. Handy to add to a script which is in your path so you can run it from any repository (a la 'svn_clean.sh').

    svn status | grep ^? | awk '{print $2}' | xargs rm -rf

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

display typedefs, structs, unions and functions provided by a header file
will display typedefs, structs, unions and functions declared in 'stdio.h'(checkout _IO_FILE structure). It will be helpful if we want to know what a particular header file will offer to us. Command 'cpp' is GNU's C Preprocessor.
