{
A[$1]; # Build array on the first column of the file
next # Skip all proceeding blocks and process next line
}
$3 in A # Check in the value in column one of the second files is in the array
{
# If so print it it to file named based on $3
print > sprintf("%s.txt",$3)
}
If so, how can I adapt this code to give me only a random subset of matched lines for each array value? Is there a way to redirect the match specified by $3 in A to gshuf -n 2 before printing?

I have a file of protein sequences with headers (my source file). Based on a list of IDs (which are included in some of the headers), I'd like to print out only the specified sequences, with only the ID as header.
In other words, I'd like to search source.txt for the terms in IDs.txt, and print... (3 Replies)

I have files named with different prefixes. From each I want to extract the first line containing a specific string, and then print that line along with the prefix.

pr
PR(1) General Commands Manual PR(1)NAME
pr - print file
SYNOPSIS
pr [ option ] ... [ file ] ...
DESCRIPTION
Pr produces a printed listing of one or more files. The output is separated into pages headed by a date, the name of the file or a speci-
fied header, and the page number. If there are no file arguments, pr prints its standard input.
Options apply to all following files but may be reset between files:
-n Produce n-column output.
+n Begin printing with page n.
-h Take the next argument as a page header.
-wn For purposes of multi-column output, take the width of the page to be n characters instead of the default 72.
-f Use formfeeds instead of newlines to separate pages. A formfeed is assumed to use up two blank lines at the top of a page. (Thus
this option does not affect the effective page length.)
-ln Take the length of the page to be n lines instead of the default 66.
-t Do not print the 5-line header or the 5-line trailer normally supplied for each page.
-sc Separate columns by the single character c instead of by the appropriate amount of white space. A missing c is taken to be a tab.
-m Print all files simultaneously, each in one column,
Inter-terminal messages via write(1) are forbidden during a pr.
FILES
/dev/tty? to suspend messages.
SEE ALSO cat(1)DIAGNOSTICS
There are no diagnostics when pr is printing on a terminal.
