.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Sort \fITextFile(s)\fR using values for a key column specified by a column number or label.
Only one column key can be specified for sorting. In an event of conflict during sorting
process, two similar values for a column key are simply transferred to output files in
order of their presence in input files. Additionally, rows with empty or inappropriate
values for column key are simply placed at the end. The file names are separated by space.
The valid file extensions are \fI.csv\fR and \fI.tsv\fR for comma/semicolon and tab delimited
text files respectively. All other file names are ignored. All the text files in a
current directory can be specified by \fI*.csv\fR, \fI*.tsv\fR, or the current directory
name. The \fB\-\-indelim\fR option determines the format of \fITextFile(s)\fR. Any file
which doesn't correspond to the format indicated by \fB\-\-indelim\fR option is ignored.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-d, \-\-detail\fR \fIinfolevel\fR" 4
.IX Item "-d, --detail infolevel"
Level of information to print about lines being ignored. Default: \fI1\fR. Possible values:
\&\fI1, 2 or 3\fR.
.IP "\fB\-h, \-\-help\fR" 4
.IX Item "-h, --help"
Print this help message.
.IP "\fB\-\-indelim\fR \fIcomma | semicolon\fR" 4
.IX Item "--indelim comma | semicolon"
Input delimiter for \s-1CSV\s0 \fITextFile(s)\fR. Possible values: \fIcomma or semicolon\fR.
Default value: \fIcomma\fR. For \s-1TSV\s0 files, this option is ignored and \fItab\fR is used as a
delimiter.
.IP "\fB\-k, \-\-key\fR \fIcol number | col name\fR" 4
.IX Item "-k, --key col number | col name"
This value is mode specific. It specifies which column to use for sorting \fITextFile(s)\fR.
Possible values: \fIcol number or col label\fR. Default value: \fIfirst column\fR.
.IP "\fB\-\-keydata\fR \fInumeric | alphanumeric\fR" 4
.IX Item "--keydata numeric | alphanumeric"
Data type for column key. Possible values: \fInumeric or alphanumeric\fR. Default value:
\&\fInumeric\fR. For \fIalphanumeric\fR data values, comparison is case insensitive.
.IP "\fB\-m, \-\-mode\fR \fIcolnum | collabel\fR" 4
.IX Item "-m, --mode colnum | collabel"
Specify how to sort text files: using column number or column label.
Possible values: \fIcolnum or collabel\fR. Default value: \fIcolnum\fR.
.IP "\fB\-o, \-\-overwrite\fR" 4
.IX Item "-o, --overwrite"
Overwrite existing files.
.IP "\fB\-\-outdelim\fR \fIcomma | tab | semicolon\fR" 4
.IX Item "--outdelim comma | tab | semicolon"
Output text file delimiter. Possible values: \fIcomma, tab, or semicolon\fR
Default value: \fIcomma\fR.
.IP "\fB\-q, \-\-quote\fR \fIyes | no\fR" 4
.IX Item "-q, --quote yes | no"
Put quotes around column values in output text file. Possible values: \fIyes or
no\fR. Default value: \fIyes\fR.
.IP "\fB\-r, \-\-root\fR \fIrootname\fR" 4
.IX Item "-r, --root rootname"
New text file name is generated using the root: <Root>.<Ext>. Default new file
name: <InitialTextFileName>SortedByColumn.<Ext>. The csv, and tsv
<Ext> values are used for comma/semicolon, and tab delimited text files
respectively. This option is ignored for multiple input files.
.IP "\fB\-s, \-\-sort\fR \fIascending | descending\fR" 4
.IX Item "-s, --sort ascending | descending"
Sorting order for column values. Possible values: \fIascending or descending\fR.
Default value: \fIascending\fR.
.IP "\fB\-w, \-\-workingdir\fR \fIdirname\fR" 4
.IX Item "-w, --workingdir dirname"
Location of working directory. Default: current directory.
