I have a header which I have to add to a sorted file, however if I use
cat header sortedfile > newfile, the operation takes 2 minutes as the sorted file is over 400mb.
I have noticed that when I sort the 400mb unsorted file, this only takes 14 seconds to create the output.
As the creation of the whole file is extremely time critical, I am obliged to find the quickest way.
I thought it might be quicker to cat the file to the sort command to create the final file so I tried this (actual command)
but I dont get the header in the file.
Questions
Will cat to the sort command actually work ?
Will the header remain unsorted.
Alternatively, I can put the header in the file and sort the whole file. Is there any way to sort the file in situ so that a new file is not created ?
So, I have a file that has some duplicate lines. The file has a header line that I would like to keep at the top.
I could do this by extracting the header from the file, 'sort -u' the remaining lines, and recombine them. But they are quite big, so if there is a way to do it with a single... (1 Reply)

fc-match
FC-MATCH(1)FC-MATCH(1)NAME
fc-match - match available fonts
SYNOPSIS
fc-match [ -asvVh ] [ --all ] [ --sort ] [ --verbose ] [ [ -f format ] [ --format format ] ] [ --version ] [ --help ]
[ pattern [ element... ] ]
DESCRIPTION
fc-match matches pattern (empty pattern by default) using the normal fontconfig matching rules to find the best font available. If --sort
is given, the sorted list of best matching fonts is displayed. The --all option works like --sort except that no pruning is done on the
list of fonts.
If any elements are specified, only those are printed. Otherwise short file name, family, and style are printed, unless verbose output is
requested.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
-a Displays sorted list of best matching fonts, but do not do any pruning on the list.
-s Displays sorted list of best matching fonts.
-v Print verbose output of the whole font pattern for each match, or elements if any is provided.
-f Format output according to the format specifier format.
-V Show version of the program and exit.
-h Show summary of options.
pattern
Displays fonts matching pattern (uses empty pattern by default).
element
If set, the element property is displayed for matching fonts.
