This command can be used with xclip or xsel for use on a linux box.

If you've ever wanted to change a text files contents without having to create an intermediate file. This is it. Ex is a part of vim. The command as given will delete ALL lines containing "delete this line" from the file.

More Examples: print '%s/'this is a line'/'that is not the same line'/g\nwq' | ex file.txt will substitute the first string with the second string. print '3a\n'Inserted Line'\n.\n\nwq' | ex file.txt will insert the given line after line 3.

CAVEAT, Some distro's like the print command, others like echo with this command. Also note there are NO error messages on failure, at least that I've ever seen. Ex can also be quite fussy as to how it takes strings, parameters, etc... I use at&t's ksh syntax may very with other shells.

It is not uncommon to receive an error "Too many open files", this command allows you to change the limit for a user. This can be put into /etc/profile so that all users will have this change.

If your XML is appended to a line with a time stamp or other leading text irrelevant to the XML, then you can append a s/foo/bar/ command, like this:

There's already a proper command for what the former alternative tried to script

Well this can come handy , when you don't feel like playing with pid rather if you know

the process name say "firefox",it would kill it.The script given below would kill the process with its name given as first parameter , though not robust enough to notify that process doesn't exist , well if you know what you are doing that's wouldn't be a problem.:)

I Like copy-directory function It does the job but looks like SH**, and this doesn't understand folders with whitespaces and can only handle full path, but otherwise fine,

function copy-directory () { ; FrDir="$(echo $1 | sed 's:/: :g' | awk '/ / {print $NF}')" ; SiZe="$(du -sb $1 | awk '{print $1}')" ; (cd $1 ; cd .. ; tar c $FrDir/ )|pv -s $SiZe|(cd $2 ; tar x ) ; }

Create a single tar.gz archive

I know it's a very basic one, but it's one I keep forgetting.

To ensure that it will never come back, you can edit /etc/modprobe.d/blacklist

short command to find a string in all text files in all subdirectories, excluding all files grep does not deem text files.

input name="rid" type="TEXT"

input name="submit" value="SUBMIT" type="SUBMIT" align="center"

Then exec the command to get the response into html
