Command to extract all columns except the last few from a txt file
hello,

i have publicly available txt file with little less than 300000 rows. i want to extract from column 1 to column 218 and save it in another text file. i use the cut command but the file is saved with multiple rows from the source file onto a single row in the destination. basically it is not formatted like the source file. the source file is in the below link. i have removed the www since this is my first post and the file name is INP_psf1301.txt

cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ProspMedicareFeeSvcPmtGen/Downloads/INP_psf1301.zip


i use the following

Code:
cut -c1, 218 INP_psf1301.txt > outputfile.txt

but the resulting file is is not formatted like the original. i want the resulting file to be exactly the same except without the last few columns. i want columns 1 to 218 in the resulting file.

is there a line break or something that i should mention or would AWK command work better?

thanks

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

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 spec-
     ified, 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.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
