NAME¶
colrm —
remove columns from a
file
SYNOPSIS¶
DESCRIPTION¶
The
colrm utility removes selected columns from the lines of a
file. A column is defined as a single character in a line. Input is read from
the standard input. Output is written to the standard output.
If only the
start column is specified, columns numbered
less than the
start column will be written. If both
start and
stop columns are
specified, columns numbered less than the
start column
or greater than the
stop column will be written. Column
numbering starts with one, not zero.
Tab characters increment the column count to the next multiple of eight.
Backspace characters decrement the column count by one.
ENVIRONMENT¶
The
LANG,
LC_ALL and
LC_CTYPE environment variables affect the execution of
colrm as described in
environ(7).
EXIT STATUS¶
The
colrm utility exits 0 on success, and >0 if
an error occurs.
