change last character using sed

Hi everyone.

I have a bunch of files like the following one:

Code:

dn: Identifier=3AM9,c=MX,l=world

objectclass: top

objectclass: IRPerson

uid: user1@mail.com

c: MX

ispasswordexpired: false

passwordlastchangedatetime: 20130211195022

userPassword: {SHA}fGphxo74ubawYbKMNIvB7Xkhy1M:

businesscategory: 1

Identifier: 3AM9

sn: last

cn: user1 last

mail: user1@mail.com

i need to change last character from userPassword : to =
e.g.

Code:

userPassword: {SHA}fGphxo74ubawYbKMNIvB7Xkhy1M=

so far i'm only able to change the first :

Code:

$ sed '/userPassword/s/:/=/' file.ldif 



dn: Identifier=3AM9,c=MX,l=world

objectclass: top

objectclass: IRPerson

uid: user1@mail.com

c: MX

ispasswordexpired: false

passwordlastchangedatetime: 20130211195022

userPassword= {SHA}fGphxo74ubawYbKMNIvB7Xkhy1M:

businesscategory: 1

Identifier: 3AM9

sn: last

cn: user1 last

mail: user1@mail.com

Any idea?, btw, userPassword can be at the top/middle of botton of the file.

Code:

for fname in *.ldif ; do sed '/userPassword/s/:/=/' $fname ; done

Hey syg00, thaks for your quick response.

I think i didn't explain myself well. the loop is not the problem, the problem here is that my sed command is not right.

if you look close to the output my sed command's output is:

Code:

userPassword= {SHA}fGphxo74ubawYbKMNIvB7Xkhy1M:

but i want

Code:

userPassword: {SHA}fGphxo74ubawYbKMNIvB7Xkhy1M=

i need to change the last character of the line from : to =

I believe i found the answer

Code:

for i in *.ldif ; do sed '/userPassword/s/M:/M=/g' $i > "$i"_.txt; done

Pls let me know if anyone has a better idea.

Oops - sed uses anchors; "$" is end of line - maybe

Code:

sed '/userPassword/ s/:$/=/'

More generic would be to use ".$"

Thank you. I will give it a shot. Let you know.
