FMLI Commands fmlcut(1F)
NAME
fmlcut - cut out selected fields of each line of a file
SYNOPSIS
fmlcut -clist [filename]...
fmlcut -flist [-dchar] [-s] [filename]...
DESCRIPTION
The fmlcut function cuts out columns from a table or fields
from each line in filename; in database parlance, it imple-
ments the projection of a relation. fmlcut can be used as a
filter; if filename is not specified or is -, the standard
input is read. list specifies the fields to be selected.
Fields can be fixed length (character positions) or variable
length (separated by a field delimiter character), depending
on whether -c or -f is specified.
Note: Either the -c or the -f option must be specified.
OPTIONS
list A comma-separated list of integer field numbers
(in increasing order), with optional - to indicate
ranges. For example: 1,4,7; 1-3,8; -5,10 (short
for 1-5,10); or 3- (short for third through last
field).
-clist If -c is specified, list specifies character posi-
tions (for instance, -c1-72 would pass the first
72 characters of each line). Note: No space
intervenes between -c and list.
-flist If -f is specified, list is a list of fields
assumed to be separated in the file by the default
delimiter character, TAB, or by char if the -d
option is specified. For example, -f1,7 copies the
first and seventh field only. Lines with no delim-
iter characters are passed through intact (useful
for table subheadings), unless -s is specified.
Note: No space intervenes between -f and list.
The following options can be used if you have
specified -f.
-dchar If -d is specified, char is the field
delimiter. Space or other characters
with special meaning to FMLI must be
quoted. Note: No space intervenes

between -d and char . The default field
delimiter is TAB.
-s Suppresses lines with no delimiter char-
acters. If -s is not specified, lines
with no delimiters will be passed
through untouched.
