Bash script - stripping away characters that can't be used in filenames
I want to create a temp file which is named based on a search string. The search string may contain spaces or characters that aren't supposed to be used in filenames so I want to strip those out.
My thought was to use 'tr' with [:alnum:] but the result is the opposite of what I want:
Hi there, if i have some strings ie
test_324423
test_242332
test_767667
but I only want the number part (the bolded bit) how do I strip the leftmost 5 characters from the output so that i will have just
324423
242332
767667
any help would be greatly appreciated

I'm trying to search all .odt files in a directory for a string in the text of the file.
I've found a bash script that works, except that it can't handle whitespace in the filenames.

hello,
I'm trying to figure out which tool is best for recursively renaming and files or folders using the characters \/*?”<>| in their name. I've tried many examples that use Bash, Python and Perl, but I'm not much of a programmer I seem to have hit a roadblock.
Does anyone have any... (15 Replies)
I wrote myself a small little shell script to clean up a file I have issues with. In particular, I am stripping down a fully qualified host/domain name to just the hostname itself. The script works, but from a performance standpoint, it's not very fast and I will be working with large data sets.

ustrtok
ustrtok(3alleg4) Allegro manual ustrtok(3alleg4)NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *ustrtok(char *s, const char *set);
DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be
searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always
copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the
same time). Example:
char *word;
char string[]="some-words with dashes";
char *temp = ustrdup(string);
word = ustrtok(temp, " -");
while (word) {
allegro_message("Found `%s'
", word);
word = ustrtok(NULL, " -");
}
free(temp);
RETURN VALUE
Returns a pointer to the token, or NULL if no more are found.
