Loops And Such Options

[bam]

I have this so far:

CODE

for item in dupes[]:
  mydupeitem=item
  for item in filter[]:
     if mydupeitem[2:] = item:
        pass
     else
        write......etc.

now is there anything wrong with this? it wipes out my entire bash history, so it never gets to the write statement. filter[] is just a list of filters(strings) and dupes[] is just a list of strings as well, basically i an 'cleaning' my bash history at logoff, I have a remove duplicates script running and it sorts but I would like to remove any "cd blahblah" and rm's mv's etc. any ideas, I am new to python, so any help would be great.

well here is the end result, I think I am getting ahold of it

#!/usr/bin/env python

import os
import fileinput

fileToSearch="/home/zaurus/.bash_history"

#filterlist for non-saves, just add as needed
filterlist=[ "cd","mv","cp","df","exit"]
filteredlist=[]
mylist=[]
noDupes=[]

[mylist.append(line) for line in fileinput.input( fileToSearch )]
fileinput.close()

[noDupes.append(j) for j in mylist if not noDupes.count(j)]
noDupes.sort

filteredlist=noDupes
os.remove(fileToSearch)
fileToOutput = open( fileToSearch, 'w' )

[filteredlist.remove(y) for x in filterlist for y in noDupes if x == y[0:len(x)] ]
[fileToOutput.write(item) for item in filteredlist]
fileToOutput.close()

basically run this under .bash_logout to clean up my bash_history file of duplicates and unwanted commands, eventually I will have it check against "valid" bash commands/executables as well.
