1- I tried to turn text to one array and replace them something like this:
Code:
text=(
a a a a a a a a a a
a a a a a a a a a a
)
Get the number of items
number=${#text[@]}
Get half of it
half=$((number/2))
In a loop from 1 to the half of the text get random number and using it as index change item in text array
for i in $(seq $half); {
rnd=$((RANDOM % (number-1)))
text[$rnd]=b
}
Echo result
echo ${text[@]}
But this code doesn't keep the new line and echo all text in one line and my text is so big about 15 Gb and can't put it in one array.
2- Choose randomly from all occurrences of one word or token in the whole text.
simply can get number of repetition by something like this ( grep "a" | wc -l )
3- I can use python to do this but my text is huge and I want to use bash since it is faster than python. In python I use a set contains (a,b) and in replace function use a random function to choose (a or b) from that set.
4- I use Ubuntu 18.04, sed (GNU sed) 4.4, GNU Awk 4.1.4, API: 1.1 (GNU MPFR 4.0.1, GNU MP 6.1.2)
5- I simplify the problem, the main problem is that: I want to normalize a text corpus for training a tri-gram language model, in the language model, the sequence of words is important. I normalize the numbers to letters so for example, I convert all 30 to thirty but we use often half instead of thirty for reporting hour (e.g 8:30). I want to replace randomly things like this not whole of them.

Hi there!
I am really enjoying working with sed. I am trying to come up with a sed command to replace some occurrences (not all) in the same line, for instance:

XmbDrawText(3X11)XmbDrawText(3X11)NAME
XmbDrawText, XwcDrawText - draw text using multiple font sets
SYNOPSIS
void XmbDrawText(display, d, gc, x, y, items, nitems)
Display *display;
Drawable d;
GC gc;
int x, y;
XmbTextItem *items;
int nitems;
void XwcDrawText(display, d, gc, x, y, items, nitems)
Display *display;
Drawable d;
GC gc;
int x, y;
XwcTextItem *items;
int nitems;
ARGUMENTS
Specifies the drawable. Specifies the connection to the X server. Specifies the GC. Specifies an array of text items. Specifies the
number of text items in the array. Specify the x and y coordinates.
DESCRIPTION
The XmbDrawText and XwcDrawText functions allow complex spacing and font set shifts between text strings. Each text item is processed in
turn, with the origin of a text element advanced in the primary draw direction by the escapement of the previous text item. A text item
delta specifies an additional escapement of the text item drawing origin in the primary draw direction. A font_set member other than None
in an item causes the font set to be used for this and subsequent text items in the text_items list. Leading text items with a font_set
member set to None will not be drawn.
XmbDrawText and XwcDrawText do not perform any context-dependent rendering between text segments. Clients may compute the drawing metrics
by passing each text segment to XmbTextExtents and XwcTextExtents or XmbTextPerCharExtents and XwcTextPerCharExtents. When the XFontSet
has missing charsets, each unavailable character is drawn with the default string returned by XCreateFontSet. The behavior for an invalid
codepoint is undefined.
STRUCTURES
The XmbTextItem structure contains:
typedef struct {
char *chars; /* pointer to string */
int nchars; /* number of bytes */
int delta; /* pixel delta between strings */
XFontSet font_set; /* fonts, None means do not change */ } XmbTextItem;
The XwcTextItem structure contains:
typedef struct {
wchar_t *chars; /* pointer to wide char string */
int nchars; /* number of wide characters */
int delta; /* pixel delta between strings */
XFontSet font_set; /* fonts, None means do not change */ } XwcTextItem;
