[CentOS] Scripting help please....

[Arturas Mr.]

I think it can be optimized, and if programing language doesn't matter:
#!/usr/bin/python

file="test.txt"
fl = open(file,'r')
toParse = fl.readlines()
fl.close()
dublicates = []
firstOne = []
for ln in toParse:
    ln=ln.strip()
    lnMap = ln.split(':')
    target = lnMap[2]
    if target in firstOne:
        if not target in dublicates:
            dublicates.append(target)
    else:
        firstOne.append(target)
for ln in toParse:
    ln = ln.strip()
    lnMap = ln.split(':')
    target = lnMap[2]
    if target in dublicates:
        print ln
