That will not work, since then all every time all lines that are not equal to the search string, will get printed.. You would need to test grep's return code and print "$line" if it is non-zero...
The sed command will not work because of the / delimiter, the is also contained in the files so that breaks the command... You would need to use another delimiter..
try:
Code:
awk 'NR==FNR{A[$1]; next} !($2 in A)' file1 file2

Trying to run a script as a different user (sudo userx inside the script) but after I call the script it just sits in memory until I <ctrl D>. If I do whoami before the <ctrl D> the system returns the userid that was invoked in the script.
Is there any way to get around this behavior?
TIA,... (3 Replies)
I have a line that gets pulled from a database that has a variable number of fields, fields can also be of a variable size. Each field has a variable number of spaces between them so there is no 'defined' delimiter. The LastData block is always a single word.

Dear all,
I am using sed as an alternative to grep in order to get a specific line from each of multiple files located in the same directory. I am using sed because it prints the lines in the correct order (unlike grep).
When I write sed code that prints out the output I get it correct, but... (1 Reply)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1).
BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
