Cut command, no input delim, output delim not working
Hello,
I'm using cygwin on my Windows 7 machine.
From the man pages of cut:
--output-delimiter=STRING
use STRING as the output delimiter the default is to use the input delimiter
I tried the following commands and got the error messages:
Code:
$ cut -c1-10,20-30 -d --output-delimiter=| filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
-bash: filename: command not found
$ cut -c1-10,20-30 -d --output-delimiter="|" filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
$ cut -c1-10,20-30 -d --output-delimiter='|' filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
$ cut -c1-10,20-30 -d --output-delimiter'|' filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
$ cut -c1-10,20-30 -d --output-delimiter| filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
-bash: filename: command not found
$ cut -c1-10,20-30 -d --output-delimiter"|" filename
cut: the delimiter must be a single character
Try `cut --help' for more information.
Is it possible that you cannot specify a output delim if you don't specify an input delim? What if there is no input delim in the file...such as a fixed length file and you want an output delim?
Can anyone shed some light on this???
Thanks in advance!

Hi guys,
I need to cut the first 12 system processes from the command ps -A. I know that the cut command forms part of the pipeline but can't understand how to cut the first 12 lines and later display them on standard output. Please help!
Many thanks, Jared. (3 Replies)
hello,
i use following command:
md5sum TEST.xml
the output looks like:
900hjidur84hjr938ikv TEST.xml
as you can see, the first part is the md5 code, the second part is the file name, but i only want the first part(md5 code), and save it to a file, how to do that? thanks. (2 Replies)
I can not make it work, it prints \t rather than introduce tabs.
cut -d "," -f 4,8 Samples.csv --output-delimiter="\t" | sort > out
Since I am running this command within a shell script, I tried manually inserting tab in this command, still does not work. I am using bash shell

cut
cut(1) General Commands Manual cut(1)Name
cut - cut out selected fields of each line of a file
Syntax
cut -clist [file1 file2...]
cut -flist [-dchar] [-s] [file1 file2...]
Description
Use the command to cut out columns from a table or fields from each line of a file. The fields as specified by list can be fixed length,
that is, character positions as on a punched card (-c option), or the length can vary from line to line and be marked with a field delim-
iter character like tab (-f option). The command can be used as a filter. If no files are given, the standard input is used.
Use to make horizontal ``cuts'' (by context) through a file, or to put files together in columns. To reorder columns in a table, use and
Options
list Specifies ranges that must be a comma-separated list of integer field numbers in increasing order. With optional - indicates
ranges as in the -o option of nroff/troff for page 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 Specifies character positions to be cut out. For example, -c1-72 would pass the first 72 characters of each line.
-flist Specifies the fields to be cut out. For example, -f1,7 copies the first and seventh field only. Lines with no field delim-
iters are passed through intact (useful for table subheadings), unless -s is specified.
-dchar Uses the specified character as the field delimiter. Default is tab. Space or other characters with special meaning to the
shell must be quoted. The -d option is used only in combination with the -f option, according to XPG3 and SVID2/SVID3.
-s Suppresses lines with no delimiter characters. Unless specified, lines with no delimiters are passed through untouched.
Either the -c or -f option must be specified.
Examples
Mapping of user IDs to names:
cut -d: -f1,5 /etc/passwd
To set name to the current login name for the csh shell:
set name=`who am i | cut -f1 -d" "`
To set name to the current login name for the sh, sh5, and ksh shells:
name=`who am i | cut -f1 -d" "`
Diagnostics
"line too long" A line can have no more than 511 characters or fields.
"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.
"no fields" The list is empty.
