Manpages TRSection: FSF (1)Updated: July 2001 Index Return to Main Contents NAMEtr - translate or delete charactersSYNOPSIStr [OPTION]... SET1 [SET2]DESCRIPTIONTranslate, squeeze, and/or delete characters from standard input, writing to standard output.
SETs are specified as strings of characters. Most represent themselves. Interpreted sequences are:
Translation occurs if -d is not given and both SET1 and SET2 appear. -t may be used only when translating. SET2 is extended to length of SET1 by repeating its last character as necessary. Excess characters of SET2 are ignored. Only [:lower:] and [:upper:] are guaranteed to expand in ascending order; used in SET2 while translating, they may only be used in pairs to specify case conversion. -s uses SET1 if not translating nor deleting; else squeezing uses SET2 and occurs after translation or deletion.
