Here is a hack with sed.
The \(\([^|]*|\)\{10\}X*\) matches the first 10 fields plus already substituted Xes in field 11, and is put back as \1.
The 4 digit look-ahead \([0-9]\{4\}\) is put back as \3.
The one [0-9] is really substituted by the X.
The whole thing repeats in a loop, until nothing is left that can be substituted. (A /g option does not work because it cannot repeat on anything before the last matched character i.e. the look-ahead.)
A solution with awk or perl or bash would look simpler, because you can split on "|" and only work on field 11.
How is it possible under UNIX to restrain the number of digits of the PID number?
For instance, we have a product that generates a PID of 7 digits, and we would like to have only 6 digits maximum instead for the PID.
Thank you for your help. (1 Reply)

split
SPLIT(1) General Commands Manual SPLIT(1)NAME
split - split a file into pieces
SYNOPSIS
split [ option ... ] [ file ]
DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa,
xab, and so on to xzz. The options are
-n Split into n-line pieces.
-e expression
File divisions occur at each line that matches a regular expression; see regexp(6). Multiple -e options may appear. If a subex-
pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex-
pression.
-f stem
Use stem instead of x in output file names.
-s suffix
Append suffix to names identified under -e.
-x Exclude the matched input line from the output file.
-i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
