Tech-Recipes: Remove ^M characters at end of lines in vi | UNIX | Tech-Recipes

  • bofh468 · 5 years ago
    Another way to do this is with the dos2unix utility. You can also use unix2dos to add in the extra ^M (carriage-return) characters to a text file so it's readable under DOS.

    Where foo is the file that has the control M's

    cat foo | col -b > foo2

    Thank you, original post did not work for me, but this did.

    type the following command:

    :%s/<control-v><control-m>//g

    ^M is the result of a control V, control M at the end of the line. if you actually hit control-v then control-m, "^M" will appear and will get rid of the character at the end of the line. hope this helps someone!!!

    Hi,

    THere is lot of non-continous blank lines in my shell. I want to find the blank line and I want to remove it. What is the command for that?

  • qmchenry · 3 years ago
    If you want to remove all blank lines in your file, search for empty lines and replace them with nothing.. since ^ means beginning of line and $ means end of line, ^$ means a blank line, so

    :%s/^$//g


    will find blank lines and make them disapear.

    All- I need to clean a bunch of files in UNIX that contain the ^M characters.

    While I can do each one individually by :%s/^M//g I would like to know if there is an easy command line execution to serarch for any files containing the errors and correct them.

    I tried this for all *.sql files in a given directory, but it didn't work:

    for name in `ls *.sql` ; do sed 's/^M//' $name > ${name/.sql/N.sql} ; mv ${name/.sql/N.sql} $name ; done

    If anyone has a suggestion or knows a simple script that can be run please let me know.

    Thanks

    You could try using sed, the stream editor - it works on similar principles to vi's replace tool, but you can pipe into and out of it.

    So, to change one file:
    cat fileName | sed s/<ctrl-v><ctrl-m>//g >tmp && mv tmp fileName

    Do NOT try to read from and write to the same file in one pipe, or you'll blank the file

    To change all files in a directory with the .sql ending, run the following script whilst inside that directory:
    #/bin/ksh
    for fileName in $(ls *.sql); do
    cat $fileName | sed s/^M//g >tmp && mv tmp $fileName
    done

    (bear in mind to enter ^M you need to enter <ctrl-v><ctrl-m> as above.

    Hope that helps people

    another way to get rid of those ^M's
    :%s/\r//g
    btw other systems then *nix are treating newlines differently :P

    I am trying ti get the diff of a file into a temp.txt file.
    When I do :%s/^M//g in my file, it says "Pattern not Found: ^M".
    But when I see the temp.txt file for the diff it shows ^M on all the lines.
    Help me out for this, I dont want ^M in temp.txt file
