Shell Programming and Scripting

Hello,

In a shell script I am writing I execute this command:

uniq -c names1.tmp > names2.tmp

In names2.tmp I get these results:

4 user
2 username
1 users
1 veriano
1 victoria

I need to isolate the names in this file and put it in another file. However it seems that the number and name are considered one field, f7 so I cannot seem to use the cut command to get the names. Any ideas on how I can do so?

Code:

cut -d" " -f 2 infile > outfile

It's not working. I get nothing. The only difference here is you declared the delimiter before the field but the result is the same.... I have cut and paste the file I need to work on below. As you can see there is a huge tab. For some reason the number and name are considered field 7. When I cut f 7 I get the number and name. I hope someone can help me solve this strange problem.

1 Aaliyah
1 Aaron
1 Aba
1 Abel
1 Amanda
1 Andrew
1 Ashley
1 Beavis
1 Buster
1 Cowboys
1 Dakota
1 Dallas
1 Dolphin
1 Friends
1 George
1 Hatton
1 Hockey
1 Internet
1 Jessica
1 Jewel
1 Jordan
1 Justin
2 Maddock

I am using the following:

# cut --version
cut (coreutils) 5.0

I can't see any tabs. Check your post. You can post code and logs etc. inside [ code ] and [ /code ] tags so most formatting won't get list.
Also by what you present as input, I can't see any field number 7. All I see is 2 fields per row, considering the space is the field separator.

Try to post your input and desired ouput with all field and tabs etc. so we can give a working example.
Without seeing your real input/desired output, you could check to extract the wanted fields maybe with awk, assuming that the field separator is any kind of blank/space/tab and that you have at least 7 fields per row/line:

Code:

awk '{print $7}' infile

I am as dumbfounded as you are.

Like I said I execute the following command: uniq -c names1.tmp > names2.tmp

names1.tmp is as follows (partial listing):

Code:

griselda
gsm
gsm
gsm
guest
guest
guest
guest
guest
guest
guest
guest
guest
guest
hammer
happy
harley
hayashi

We get names2.tmp (partial listing):

Code:

      1 Aaliyah
      1 Aaron
      1 Aba
      1 Abel
      1 Amanda
      1 Andrew
      1 Ashley
      1 Beavis
      1 Buster
      1 Cowboys
      1 Dakota
      1 Dallas
      1 Dolphin
      1 Friends
      1 George
      1 Hatton
      1 Hockey
      1 Internet
      1 Jessica
      1 Jewel
      1 Jordan
      1 Justin
      2 Maddock

So you see there is a large indent on the left. When I execute the cut command command on f2 I get nothing. When I execute on f7 I get the following which is weird:

Code:

1       Abel
1       Amanda
1       Andrew
1       Ashley
1       Beavis
1       Buster
1       Cowboys
1       Dakota
1       Dallas
1       Dolphin
1       Friends
1       George
1       Hatton
1       Hockey
1       Internet
1       Jessica
1       Jewel
1       Jordan
1       Justin
2       Maddock

cutting on f2 yields nothing....

Hehe, assuming I can see it now, but I still can't see field number 7 or what you understand by f7, try out:

Code:

awk '{print $2}' infile

If that is what you are looking for, redirect it in the desired file.

Do you want to know something weird? I left out the -d option for delimiter and I ran

cut -f2 names2.tmp ...guess what? I got the right answer:

Code:

undead
unix
up
upload
user
username
users
veriano
victoria
walter
wayne
web
webadm
webadmin
webdev
