Hello!
I am writing a program to run through two large lists of data (~300,000 rows), find where rows in one file match another, and combine them based on matching fields. Due to the large file sizes, I'm guessing AWK will be the most efficient way to do this. Overall, the input and output I'm... (5 Replies)
Hi folks,
Lets say I have the following text file:
name, lastname, 1234, name.lastname@test.com
name1, lastname1, name2.lastname2@test.com, 2345
name, 3456, lastname, name3.lastname3@test.com
4567, name, lastname, name4.lastname4@test.com
I now need the following output:

Hi experts,
I need to print the first field first then last two fields should come next and then i need to print rest of the fields.

Expected output:
a1,b1,b2,abc,jsd,fhf,fkk... (6 Replies)
Dear AWK-experts!
I did get stuck in the task of combining files after matching fields, so I'm still awkward with learning AWK.
There are 2 files: one containing 3 columns with ID, coding status, and score for long noncoding RNAs:
file1 (1.txt) (>5000 lines)

Hi all,
I want to extract rows with the pattern ALPHANUMERIC/ALPHANUMNERIC in the 2nd column.

I tried this and it doesn't sort on the difference field .. Appreciate your help.

In the below I am trying to use awk to match all the $13 values in input, which is tab-delimited,
that are in $1 of gene which is just a single column of text.
However only the line with the greatest $9 value in input needs to be printed.
So in the example below all the MECP2 and LTBP1... (0 Replies)

Trying to use awk to match the contents of each line in file1 with $5 in file2. Both files are tab-delimited and there may be a space or special character in the name being matched in file2, for example in file1 the name is BRCA1 but in file2 the name is BRCA 1 or in file1 name is BCR but in file2...

git-check-ignore
GIT-CHECK-IGNORE(1) Git Manual GIT-CHECK-IGNORE(1)NAME
git-check-ignore - Debug gitignore / exclude files
SYNOPSIS
git check-ignore [options] pathname...
git check-ignore [options] --stdin
DESCRIPTION
For each pathname given via the command-line or from a file via --stdin, check whether the file is excluded by .gitignore (or other input
files to the exclude mechanism) and output the path if it is excluded.
By default, tracked files are not shown at all since they are not subject to exclude rules; but see '--no-index'.
OPTIONS -q, --quiet
Don't output anything, just set exit status. This is only valid with a single pathname.
-v, --verbose
Also output details about the matching pattern (if any) for each given pathname. For precedence rules within and between exclude
sources, see gitignore(5).
--stdin
Read pathnames from the standard input, one per line, instead of from the command-line.
-z
The output format is modified to be machine-parseable (see below). If --stdin is also given, input paths are separated with a NUL
character instead of a linefeed character.
-n, --non-matching
Show given paths which don't match any pattern. This only makes sense when --verbose is enabled, otherwise it would not be possible to
distinguish between paths which match a pattern and those which don't.
--no-index
Don't look in the index when undertaking the checks. This can be used to debug why a path became tracked by e.g. git add . and was
not ignored by the rules as expected by the user or when developing patterns including negation to match a path previously added with
git add -f.
OUTPUT
By default, any of the given pathnames which match an ignore pattern will be output, one per line. If no pattern matches a given path,
nothing will be output for that path; this means that path will not be ignored.
If --verbose is specified, the output is a series of lines of the form:
<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
<pathname> is the path of a file being queried, <pattern> is the matching pattern, <source> is the pattern's source file, and <linenum> is
the line number of the pattern within that source. If the pattern contained a ! prefix or / suffix, it will be preserved in the output.
<source> will be an absolute path when referring to the file configured by core.excludesFile, or relative to the repository root when
referring to .git/info/exclude or a per-directory exclude file.
If -z is specified, the pathnames in the output are delimited by the null character; if --verbose is also specified then null characters
are also used instead of colons and hard tabs:
<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
If -n or --non-matching are specified, non-matching pathnames will also be output, in which case all fields in each output record except
for <pathname> will be empty. This can be useful when running non-interactively, so that files can be incrementally streamed to STDIN of a
long-running check-ignore process, and for each of these files, STDOUT will indicate whether that file matched a pattern or not. (Without
this option, it would be impossible to tell whether the absence of output for a given file meant that it didn't match any pattern, or that
the output hadn't been generated yet.)
Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by
overfilling an input buffer or reading from an empty output buffer.
EXIT STATUS
0
One or more of the provided paths is ignored.
1
None of the provided paths are ignored.
128
A fatal error was encountered.
