Readd all files is missing from svn repo

When working on a big proeject with SVN, you create quite much files, for now! Can just sit here and type svn add for all of them! svn status will return a list of all of file which get ?(not add), "M"(Modified), "D"(Deleted)! This code just grep "?" flag, then add it into SVN again!
This is sample output - yours may be different.
1

svn status | grep "^\?" | awk '{print $2}' | xargs svn add

Extract multiple file in a directory

You can flexibly change file pattern(*.tar.gz) and uncompress command to other job! Example, remove all files : for i in *.tar.gz; do rm $i; done (Just for example, because if you really want to remove file, simply use wildcard like this rm *.tar.gz)
This is sample output - yours may be different.
0

for i in *.tar.gz; do tar -xzf $i; done

Add a shadow to picture

Please take notice that if you are going to use an JPG file for shadow effect, let change -background none to -background white! Because -background none make a transparent effect while JPG doesn't support transparent! And when viewing, you will get a bacl box! So we will use an white background under! We can use other color as well!
This is sample output - yours may be different.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get all mac address

Find all plain text files that do not contain STRING

Find the package that installed a command

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Quick find function

A function that allows you to perform a case-insensitive search in the current directory, and directories in the current directory (but no further), for files containing the first argument anywhere in their names.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

monitor what processes are waiting for IO interrupts

Adding Prefix to File name

Good old bracket expansion :-) For large numbers of files, "rename" will spare you the for-loop, or the find/exec...

Rename files in batch

Kill all processes that listen to ports begin with 50 (50, 50x, 50xxx,...)

Run netstat as root (via sudo) to get the ID of the process listening on the desired socket. Use awk to 1) match the entry that is the listening socket, 2) matching the exact port (bounded by leading colon and end of column), 3) remove the trailing slash and process name from the last column, and finally 4) use the system(…) command to call kill to terminate the process. Two direct commands, netstat & awk, and one forked call to kill. This does kill the specific port instead of any port that starts with 50. I consider this to be safer.

Stay in the loop…

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
