Hi all. If I have a unix directory with multiple files, lets say, I have some with .dat extensions, some with .txt extensions, etc etc.
How in a script would I provide a count of all the different file types (so, the different extensions, I guess) in the directory??
So if I had:
test.dat... (6 Replies)
I need "awk solution" for simple counting!
File looks like:
STUDENT GRADE
student1 A
student2 A
student3 B
student4 A
student5 B
Desired Output:
GRADE No.of Students
A 3
B 2
Thanks for awking! (4 Replies)

count=0while test $count -lt 10do#do something for 0,1,2...9 count=$(($count+1))doneIt doesnt work. Can anyone tell me what im doing wrong?? thanks (11 Replies)
Hi,
I want to count how many rows are in a file for a specific column.
eg.
K NM
K NM
K NM
K JK
K NM
K JK
K NM
so the file is tab-delimited. I want to count how many rows are in column 2 and how many NMs there are.
I used awk
awk '{OFS="\t"}; {count++} {print i,... (3 Replies)

I’m new to Linux script and not sure how to filter out bad records from huge flat files (over 1.3GB each). The delimiter is a semi colon “;”

TABS(1) BSD General Commands Manual TABS(1)NAME
tabs -- set terminal tabs
SYNOPSIS
tabs [-n|-a|-a2|-c|-c2|-c3|-f|-p|-s|-u] [+m[n]] [-T type]
tabs [-T type] [+[n]] n1[,n2,...]
DESCRIPTION
The tabs utility displays a series of characters that first clears the hardware terminal tab settings and then initializes the tab stops at
the specified positions and optionally adjusts the margin.
The phrase "tab-stop position N" means that, from the start of a line of output, tabbing to position N shall cause the next character output
to be in the (N+1)th column on that line.
The following options are supported:
-n Specifies repetitive tab stops separated by a uniform number of columns, n, where n is a single digit decimal number. The
default usage of tabs with no arguments is equivalent to tabs -8. When -0 is used, the tab stops are cleared and no new ones
set.
-a Assembler, applicable to some mainframes. Equivalent to tabs 1,10,16,36,72 .
-a2 Assembler, applicable to some mainframes. Equivalent to tabs 1,10,16,40,72
-c COBOL, normal format. Equivalent to tabs 1,8,12,16,20,55
-c2 COBOL, compact format (columns 1 to 6 omitted). Equivalent to tabs 1,6,10,14,49
-c3 COBOL, compact format (columns 1 to 6 omitted), with more tabs than -c2. Equivalent to tabs
1,6,10,14,18,22,26,30,34,38,42,46,50,54,58,62,67
-f FORTRAN. Equivalent to tabs 1,7,11,15,19,23
-p PL/1. Equivalent to tabs 1,5,9,13,17,21,25,29,33,37,41,45,49,53,57,61
-s SNOBOL. Equivalent to tabs 1,10,55
-T type Indicates the type of terminal.
-u Assembler, applicable to some mainframes. Equivalent to tabs 1,12,20,44
EXIT STATUS
The tabs utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
The COLUMNS and TERM environment variables affect the execution of tabs as described in environ(7).
The -T option overrides TERM. If neither TERM nor the -T option are present, tabs will fail.
SEE ALSO expand(1), stty(1), tput(1), unexpand(1), termcap(5)STANDARDS
The tabs utility conforms to IEEE Std 1003.1 (``POSIX.1'').
HISTORY
A tabs utility first appeared in PWB UNIX. This implementation was introduced in NetBSD 6.0.

BUGS
The current termcap(5) database does not define the set left soft margin 'ML' capability for any terminals.
