a vim (alghough I esteem the corresponging vi command is the same) command to insert one character only, into the text being edited. That is, I'm in command mode, I issue command INSERT, I type a character, and automatically I'm again in command mode, where INSERT is the command I do not know. I have vimtutor but do not see it explained there.
View 7 RepliesI am trying the execute the following
#!/usr/bin/python

os.system("sed -e 's#^(.*) (.*)0http://12#' t2.txt > t3.txt")
os.system("cat t3.txt | sort | uniq -c | sort -rn | head > t4.txt")
But I receive the following error message.
sed: -e expression #1, char 27: unterminated `s' command
Just in case someone can reply a silly question, I've quite forgot the vi/vim command to bring the cursor to the 1st char in the current line. I do remember that for bringing it to EOL is '$'.

Programming in C.I have two char arrays.char buf1[1024];char buf2[1024];Aren't buf1 and buf2 also pointers?I read in 1024 bytes into buf1 which contain about 300 bytes of characters with newlines. The data is basically a few English sentences. I'm trying to scan buf1 for newlines and then stop at the 1st newline and copy the rest of the data from that 1st newline into buf2.So I run a for loop to look for that new line.

Line 43 points at the snprintf() command.I think the error has to do with the function being virtual and the const after the function definition, however although I have been looking really hard I have not being able to find the reason nor the solution to the problem.
One workaround that I know is moving the block of source withing the virtual function, in the constructor, however having read around (boost library exceptions tutorials) it specifically said that formating of errors messages should not take place withing the construction of objects because we are risking throwing an exceptions and messing up the flow order.
i define variable of type char (range -128 to 127). when i tried to print the value after assigning a -ve value to it it displaying a +ve value of that -ve value(256+value).

View 5 Replies View RelatedI've been reading tutorials of Linux sed command, but haven't got anything yet. the problem is : I want to insert a line into my DNS database file which has a pattern like below:

If so, where do I edit to add the mount command?

I've been using Vim for several months now via my web host (they allow putty access). All of a sudden, the escape key has become unresponsive. I cannot exist insert or any other mode by simply hitting escape. I have to hit F1 which brings up the help in vim and kicks me into command mode.
I'm most certain that my escape key on my keyboard is functioning fine since all of my windows shortcuts that use the escape key operate normally.
I know this is a ridiculous question and I'm certain there's a lot more to look into regarding a solution. What I really need is a solid lead as to where to start looking.

I'm a newbie on Linux and had to do something like this with the zip command:
My folder structure inside a zip file abc.zip is code...
It would move into abc.zip as folder3/textfile.txt (the hierarchy preserved)
Also used a -j switch (help said it junked the path info and it did but) - it would move only into abc.zip and sit at the same level as folder1 and folder2 instead of replacing the textfile.txt within abc.zip/folder1
My question is - I want to replace the abc.zip/folder1/textfile.txt with the one inside seconddir/folder3/textfile.txt.
How do I achieve this via the command line interface?
How do I get to insert mode in gedit? Why is there no documentation to do this? My Gedit comes up in overlay mode.
