fmlcut(1F) FMLI Commands fmlcut(1F)NAMEfmlcut - cut out selected fields of each line of a file
SYNOPSISfmlcut-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 implements the projection of
a relation. fmlcut can be used as a filter; if filename is not speci‐
fied or is −, the standard input is read. list specifies the fields to
be selected. Fields can be fixed length (character positions) or vari‐
able 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 positions (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 inter‐
venes 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 characters. If -s
is not specified, lines with no delimiters will be
passed through untouched.

Example 2: Getting the current login name
The next example gets the current login name.
example% `who am i | fmlcut-f1 -d" "`

ERROR: line too long
A line has more than 1023 characters or fields, or there is no new-
line character.
ERROR: bad list for c/f option
Missing -c or -f option or incorrectly specified list. No error
occurs if a line has fewer fields than the list calls for.
ERROR: no fields
The list is empty.
ERROR: no delimiter
Missing char on -d option.
