Hello,
I need to insert a line (like a header) as the first line of a very huge file (about 3 ml rows). I am able to do it with sed, but redirecting the output and creating a new file takes quite some time. I was wondering if there was a more efficient way of doing it?

fmlcut
fmlcut(1F) 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 implements 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 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 delimiter charac-
ters 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 characters. If -s is not specified, lines with no delimiters will be passed through
untouched.
EXAMPLES
Example 1 Getting login IDs and names
The following example gets the login IDs and names.
example% fmlcut -d: -f1,5 /etc/passwd
Example 2 Getting the current login name
The next example gets the current login name.
example% `who am i | fmlcut -f1 -d" "`

fmlcut returns the following exit values:
0 when the selected field is successfully cut out
2 on syntax errors
The following error messages may be displayed on the FMLI message line:
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.
NOTES
fmlcut cannot correctly process lines longer than 1023 characters, or lines with no newline character.
