Excel sortIP macro

Found this somewhere on web several months ago. Very useful for long lists of machines that one want to order by IP addresses.

    Option Explicit
    Sub sortIP() 'sorts IP addresses
    Dim i As Long, j As Long, k As Long
    Dim IP
    Dim rg()
    Dim RangeToSort As Range
    Dim IPaddress As String
    Dim IPColumn As Long
    IPaddress = "#*.#*.#*.#*"
    Set RangeToSort = Selection
    'If just one cell selected, then expand to current region
    If RangeToSort.Count = 1 Then
    Set RangeToSort = RangeToSort.CurrentRegion
    End If
    'Check if row 1 contains an IP address. If not, it is a header row
    'first find column with IP addresses. Check row 2 since row 1 might be a Header
    IPColumn = 1
    Do Until RangeToSort.Cells(2, IPColumn).Text Like IPaddress
    If IPColumn > RangeToSort.Columns.Count Then
    MsgBox ("No valid IP address found in Row 1 or Row 2")
    Exit Sub
    End If
    IPColumn = IPColumn + 1
    If Not RangeToSort(1, IPColumn).Text Like IPaddress Then
    Set RangeToSort = RangeToSort.Offset(1, 0). _
    Resize(RangeToSort.Rows.Count - 1, RangeToSort.Columns.Count)
    End If
    'one extra column for the IP sort order
    ReDim rg(RangeToSort.Rows.Count - 1, RangeToSort.Columns.Count)
    For i = 0 To UBound(rg)
    For k = 1 To UBound(rg, 2)
    rg(i, k) = RangeToSort.Cells(i + 1, k).Text
    Next k
    IP = Split(rg(i, IPColumn), ".")
    For j = 0 To 3
    rg(i, 0) = rg(i, 0) & Right("000" & IP(j), 3)
    Next j
    Next i
    rg = BubbleSort(rg, 0)
    For i = 0 To UBound(rg)
    For k = 1 To UBound(rg, 2)
    RangeToSort.Cells(i + 1, k) = rg(i, k)
    Next k
    Next i
    End Sub
    Function BubbleSort(TempArray As Variant, d As Long) 'D is dimension to sort on
    Dim temp() As Variant
    Dim i As Integer, j As Integer, k As Integer
    Dim NoExchanges As Boolean
    k = UBound(TempArray, 2)
    ReDim temp(0, k)
    NoExchanges = True
    For i = 0 To UBound(TempArray) - 1
    If TempArray(i, d) > TempArray(i + 1, d) Then
    NoExchanges = False
    For j = 0 To k
    temp(0, j) = TempArray(i, j)
    TempArray(i, j) = TempArray(i + 1, j)
    TempArray(i + 1, j) = temp(0, j)
    Next j
    End If
    Next i
    Loop While Not NoExchanges
    BubbleSort = TempArray
    End Function

sed tricks

Filed under: scripting, transformers — Tags: , , — sandokan65 @ 15:58

These one-liners are collected from various sites and articles on web – see the list of Sources at the bottom of this posting.

  • Deleting all empty lines from the input file:
    sed ‘/^$/d’ 
  • In-place replacement:
    sed –i ‘/^$/d’ INPUTFILE
  • In-place replacement with backup of original file:
    sed –ibak ‘/^$/d’ INPUTFILE
  • In-place deletion of all occurences of a string in a file:
    sed –i ‘/WORDTOBEDELETED/d’
  • How to replace the first occurrence only (of a string match) in a file, using sed
  • Append environment variable PATH with sed:
    sed -e '/^PATH/s/"$/:\/usr\/lib\/myprog\/bin"/g' -i /etc/environment
  • Remove all whitespace from beinning of lines:
    sed 's/^[ \t]*//g' foo
  • Deleting the / from all html files contained in current folder:
    sed -i ‘s/src=”\//src=”/g’ *.html
  • Greedy matching:
    % echo "foobar" | sed 's///g'
  • Non greedy matching:
    % echo "foobar" | sed 's/]*>//g'

Command line based text replace


  • sed 's/Mark Monre/Marc Monroe/' 1.txt > 2.txt
  • find ./* -type f -exec sed -i 's///g' {} \;

The “replace” command

  • Syntax:
  • Example:
    $ replace UNIX Linux  newfile
  • Example:
    $ cat /etc/passwd | replace : '|'
  • Partial support for regular expressions: \^ – matches start of line, and $ matches end of line.
  • Example: replace all IP address start of line:
    $ replace \^  newfile
  • a bash script, ‘fixer.sh’
    replace CHANGEFROM CHANGETO $1.tmp
    rm $1
    mv $1.tmp $1

    now run this command line:

    $ grep CHANGEFROM |cut -d':' -f1 |xargs -n 1 fixer.sh

    the results is that all files in the directory (or whatever you grep for) will be changed automagically.
    just make sure the grep doesn’t include the fixer script itself, or it will die half-way through changing when execute permissions are reset!
