NAME
trs - filter replacing strings
SYNOPSIS
trs [-[r]e] 'REPLACE_THIS WITH_THAT [AND_THIS WITH_THAT]...'
trs [-[r]f] FILE
DESCRIPTION
Copy stdin to stdout replacing every occurence of given strings with other ones. This is similar to tr(1), but replaces strings, not only
single chars.
Rules (separated by whitespace) can be given directly after -e option, or can be read from FILE. Argument not preceded by -e or -f is
guessed to be a script when it contains some whitespace, or a filename otherwise.
Comments are allowed from # until the end of line. The character # in strings must be specified as #.
Standard C-like escapes a e f
v \
nn are recognized. In addition, s means a space character and ! means an empty
string.
Sets of acceptable characters at a given position can be specified between [ and ]. ASCII ranges in sets can be shortly written as
FIRST-LAST. When a set consists of only a single range, [ and ] can be omitted.
When a part of the string to translate is enclosed in {...}, only that part is replaced. Any text outside {...} serves as an assertion:
a string is translated only if it is preceded by the given text and followed by another one. { at the beginning or } at the end of the
string can be omitted. Text outside {...} is treated as untranslated.
Before the beginning of the file and after its end there are only
's. Thus, for example,
{.}
matches . on a line by itself,
including the first line, and the last one even without the
marker.
A fragment of the form ?x=N, where x is a letter A-Za-z and N is a digit 0-9, contained in the target text sets the variable x to the
value N when that rule succeeds. Similar fragment in the source text causes the given rule to be considered only if that variable has such
value. Initially all variables have the value of 0. Several assignments or conditions can be present in one rule - they are ANDed
together.
OPTIONS
-e Give the translation rules directly in the command line.
-f Get them from the file specified.
-r Reverse every rule. This affects only the next -e or -f option. Of course this doesn't have to give the reverse translation! Any
rule containing any of {}[]{}- is taken in only one direction. You may force any rule to be taken in only one direction by
enclosing the string to translate in {...}.
--help display help and exit
--version
output version information and exit
Multiple -e or -f options are allowed. All rules are loaded together then, and earlier ones have precedence.
EXAMPLE
$ echo Leeloo |trs -e 'el n e i i aqq o}
x o u'
Linux
DIFFERENCES FROM sed
The main difference between trs and sed 's///g; ...' (excluding sed's regular expressions) is that sed takes every rule in the order speci-
fied and applies it to the whole line of translated file, whereas trs examines every position and tries all rules in this place first. In
sed every next rule is fed with the text produced by the previous one, whereas in trs every piece of text can be translated at most once
(if more than one rule matches at a given position, the one mentioned earlier wins). That's why sed isn't well suited for translating
between character sets. On the other hand, tr translates only single bytes, so it can't be used for Unicode conversions, or TeX / SGML ways
for specifying extended characters.
Another example:
$ echo 642 |trs -e '4 7 72 66 64 4'
42
$ echo 642 |sed 's/4/7/g; s/72/66/g; s/64/4/g'
666
The string to replace can be empty; there must be something outside {} then. In this special case only one such create-from-nothing rule
can success at a given position. For example, }x80-xFF @ precedes every character with high byte set with @. The rule of the form
some{ thing doesn't work at the end of a file.
