I'm afraid sed (alone) can't do that, as it can't calculate nor count. On top, your request is not quite clear - does the term "char" as used by you include digits and punctuation etc, or not? Please specify. If all that is included, try a combination like

tar has the -T operand for reading patterns from a file.
Is there any way to read patterns from stdin, without creating a temp file? I would like to avoid iterating over the archive repeatedly (e.g. with a loop or xargs) as this is a large archive and we're only extracting a small number of... (2 Replies)
Hey, guys!
Trying to research this is such a pain since the read command itself is a common word. Try searching "unix OR linux read command examples" or using the command substitution keyword. :eek:
So, I wanted to use a command statement similar to the following.

strcpy
STRING(3) Library Functions Manual STRING(3)NAME
strcat, strncat, strcmp, strncmp, strcasecmp, strncasecmp, strcpy, strncpy, strlen, index, rindex - string operations
SYNOPSIS
#include <strings.h>
char *strcat(s, append)
char *s, *append;
char *strncat(s, append, count)
char *s, *append;
int count;
strcmp(s1, s2)
char *s1, *s2;
strncmp(s1, s2, count)
char *s1, *s2;
int count;
strcasecmp(s1, s2)
char *s1, *s2;
strncasecmp(s1, s2, count)
char *s1, *s2;
int count;
char *strcpy(to, from)
char *to, *from;
char *strncpy(to, from, count)
char *to, *from;
int count;
strlen(s)
char *s;
char *index(s, c)
char *s, c;
char *rindex(s, c)
char *s, c;
DESCRIPTION
These functions operate on null-terminated strings. They do not check for overflow of any receiving string.
Strcat appends a copy of string append to the end of string s. Strncat copies at most count characters. Both return a pointer to the null-
terminated result.
Strcmp compares its arguments and returns an integer greater than, equal to, or less than 0, according as s1 is lexicographically greater
than, equal to, or less than s2. Strncmp makes the same comparison but looks at at most count characters. Strcasecmp and strncasecmp are
identical in function, but are case insensitive. The returned lexicographic difference reflects a conversion to lower-case.
Strcpy copies string from to to, stopping after the null character has been moved. Strncpy copies exactly count characters, appending
nulls if from is less than count characters in length; the target may not be null-terminated if the length of from is count or more. Both
return to.
Strlen returns the number of non-null characters in s.
Index (rindex) returns a pointer to the first (last) occurrence of character c in string s or zero if c does not occur in the string. Set-
ting c to NULL works.
