Depending on your shell you could try one of these:
Code:
if [[ "$file" = objectMyMaths* ]] ||
[[ "$file" = objectMyEnglish* ]] ||
[[ "$file" = objectMyHistory* ]] ||
[[ "$file" = objectMyChemistry* ]]
then
echo {file name matches one of the string so do this }
fi
Code:
case "$file" in
objectMyMaths*|objectMyEnglish*|objectMyHistory*|objectMyChemistry*)
echo {file name matches one of the string so do this }
;;
*)
echo "No match"
;;
esac
Hi,
I have this script:
awk -v va=45 '$0~va{print}' flo2
That returns: "4526745 1234 " (this is the only line of the file "flo2".
However, I would like to get "va" to match the begining of the line, so that is "va" is different than 45 (eg. 67, 12 ...) I would not have any output. That... (3 Replies)

re_comp
RE_COMP(3) BSD Library Functions Manual RE_COMP(3)NAME
re_comp, re_exec -- regular expression handler
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
#include <unistd.h>
char *
re_comp(const char *s);
int
re_exec(const char *s);
DESCRIPTION
This interface is made obsolete by regex(3).
The re_comp() function compiles a string into an internal form suitable for pattern matching. The re_exec() function checks the argument
string against the last string passed to re_comp().
The re_comp() function returns 0 if the string s was compiled successfully; otherwise a string containing an error message is returned. If
re_comp() is passed 0 or a null string, it returns without changing the currently compiled regular expression.
The re_exec() function returns 1 if the string s matches the last compiled regular expression, 0 if the string s failed to match the last
compiled regular expression, and -1 if the compiled regular expression was invalid (indicating an internal error).
The strings passed to both re_comp() and re_exec() may have trailing or embedded newline characters; they are terminated by NULs. The regu-
lar expressions recognized are described in the manual entry for ed(1), given the above difference.
DIAGNOSTICS
The re_exec() function returns -1 for an internal error.
The re_comp() function returns ``no previous regular expression'' or one of the strings generated by regerror(3).
SEE ALSO ed(1), egrep(1), ex(1), fgrep(1), grep(1), regex(3)HISTORY
The re_comp() and re_exec() functions appeared in 4.0BSD.
