matching not just words; alternative to (\w+) ?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello , I have this file containing the following :

 export blblbb=R${oudfd}74ESE
[download]

now somtime it is exported to somthing like

export blblbb=erese
[download]

which is only a word , now is there a way to match the output for blblbb weather it contains only letters or mixed like R${oudfd}74ESE. for the second one I can do this :

if /^blblbb=(\w+)/ then I will get the whole thing erese which is good
[download]

for the second one

R${oudfd}74ESE 
if I do this 
if /^blblbb=(\w+)/ then I will only get R
[download]

so what is the way to match it if it is different . thanks

You can use the POSIX character set `graph` to do this: `/\A blblbb=([[:graph:]]+)/x` [download] `graph` matches pretty much anything printable except whitespace. Note that the double square brackets are required. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `: () { :\|:& };:` Note: All code is untested, unless otherwise stated	[reply] [d/l] [select]

Perhaps `.+` or `\S+` is what you want instead of `\w+`? duff	[reply] [d/l] [select]

Both of those will also match control characters, like ESC and NUL. Probably a bad idea. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `: () { :\|:& };:` Note: All code is untested, unless otherwise stated	[reply] [d/l]

Anonymous Monk probably does not want the whitespace in the match, so (.+) is probably not appropriate. (\s+) {Lower-case s} matches whitespace, so it will not work. Try `if /^blblbb=(\S+)/` [download] "When you are faced with a dilemma, might as well make dilemmanade. "	[reply] [d/l]
