Hi Gurus,
I am working with a korn shell script. I should replace in a very great file the character ";" with a space.
Example:
2750;~
2734;~
2778;~
2751;~
2751;~
2752;~
what the fastest method is? Sed? Awk?
Speed is dead main point, Seen the dimensions of the files

recins - insert records in a recfile SYNOPSIS
recins [OPTION]... [t TYPE] [-n NUM | -e EXPR | -q STR | -m NUM] [(-f STR -v STR]|[-R RECDATA)]... [FILE] DESCRIPTION
Insert new records in a rec database. -f, --field=STR field name; should be followed by a -v. -v, --value=STR field value; should be preceded by an -f. -r, --record=STR record that will be inserted in the file. --force insert the record even if it is violating record restrictions. --no-external don't use external descriptors. --no-auto don't insert auto generated fields. --verbose give a detailed report if the integrity check fails. -s, --password=STR encrypt confidential fields with the given password. --help print a help message and exit. --version show version and exit. Record selection options: -i, --case-insensitive make strings case-insensitive in selection expressions. -t, --type=TYPE operate on records of the specified type only. -e, --expression=EXPR selection expression. -q, --quick=STR select records with fields containing a string. -n, --number=NUM,... select specific records by position, with ranges. -R, --random=NUM select a given number of random records. If no FILE is specified then the command acts like a filter, getting the data from standard input and writing the result to standard out- put. AUTHOR
