Hello,
I have "mastered" the counting of occurrences with uniq -c.
Now I need to keep that file neat and nice and remove only the occurrence number and the space after it.
Example:
Code:
1286456 aaa
164758 aab aaa
112345 aac aaf
should be turned into:
Code:
aaa
aab aaa
aac aaf
I have tried without too much success "cut" and was pointed towards awk and sed, alas ... I am posting in the dummy section for a reason...
Code:
awk {'print $2'} foobar.txt > foobar_1.txt #also removes the spaces included in the lines
And
Code:
sed 's/^\ \+[0-9]\+\ //' foobar.txt > foobar_1.txt[/I] # does not work (I was told that I have FreeBSD and not GNU sed)
Does anyone could point me in the right direction?
Thank you very much in advance.

uniq
UNIQ(1) General Commands Manual UNIQ(1)NAME
uniq - report repeated lines in a file
SYNOPSIS
uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ]
DESCRIPTION
Uniq reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are removed;
the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found; see sort(1). If the -u flag
is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of just the repeated
lines is to be written. The normal mode output is the union of the -u and -d mode outputs.
The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of
times it occurred.
The n arguments specify skipping an initial portion of each line in the comparison:
-n The first n fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab charac-
ters separated by tabs and spaces from its neighbors.
+n The first n characters are ignored. Fields are skipped before characters.
