Hi,
I have the following script. When the number to the right of 'seq' is
large (as 10 in the example), the script will hang. But when the
number is small (say 1000), the script can be finished correctly. I
suspect that the problem is that there is a limit on the buffer size
for fifo. Is it so
Hi,
Suppose I have a file 'a/b/c/d/e/f', I want to copy it to 'target'
with the parent 'd/e'. I.e., the resulted file is 'target/d/e/f'.
I can make a bash script to do so, but I wondering if there is an
existing command or option. Thanks!

Hello,
The modifiers of -k are discussed in the examples in 'info sort'
rather than in the main entry of "-k". I feel that this be improved by
clearly describe each modifier under the main entry of "-k". It is not
very clear to how many modifiers there are.

I'm trying to cp -MM to -M. But so far I don't have a way to do it.
Would you please let me know what is the correct way to cp from -MM to
-M?
$ cp -r -- -MM/ -- -M
cp: target `-M' is not a directory
$ ll -go
total 0

Hi,
-k option of sort only allow a range of files. But I would like a list
of fields. For example, field 7, field 3 then field 8. Would you
please let me know how to do it?

Hi,
I need to reorder the fields in a file. But the -f option can not be
used to reorder field 1 and field 2.
Basically, I want the original 1st field as the new 2nd field and the
original 2nd field the first. Is reordering fields possible with cut.
$ cat input.txt

Hi,
I don't think that I completely understand what key means. In the
following example, I thought that --key=2 should order the lines by
the 2nd letter in each line without reordering the lines with the same
2nd letter. But it turns out my understanding is not correct. For
example, "u a" was befo

When I use wc -l *.txt, it show the total number of lines at the end.
I don't necessary need this last line. Is there a way to disable it?

ls -go gives me permission and file sizes. But I only want to show
time and file names. Would you please let me know what command to use?

I'm wondering if there is any tool that can do almost exact the same
thing as mv, but it can maintain symbolic links.
mv doens't maintain relative symbolic links. For example, I have file
/tmp/A/file1.txt and a symbolic link /tmp/file1.txt that point to
A/file.txt (by the relative path). If I mv /
'ls -l' shows the symbolic link and its target. I could parse the
output. But I'm wondering whether there is a convenient command that
only print the target if it is a symbolic link otherwise print
nothing? Thank you for your help.
I don't see an option to list only symbolic link with ls. Could
somebody let me know if there is such an option?
'touch' will not make the file size empty if the file is not empty. I
don't not want to use 'rm -f' first then touch because I might
accidentally remove something if I type anything wrong. Could somebody
let me a better way to create an empty file?
Suppose I have directory a and b, the following command will copy the
content of a to b/a, rather than overwrite the directory 'b' by the
directory 'a'. I'm wondering if there is an option to overwrite 'b'?
cp -r a b
I don't see an option that sorts ls result by file size. Could
somebody let me know if there is such an option?

The above alias doesn't distinguish the color for a symbol link
pointing to a file and a symbol link pointing to a dir. I'm wondering
if there is a way to configure it to do so?
I have the following file head.txt. I'm wondering what the correct way
is to change the tab to a backslash and the character 't'.
$ tr "\t" "\\t"
I'm wondering if there is a similar program to 'head' that accepts gz
files. (just as zgrep to grep)
