Frequently used file test operators-ongoing updates - e -- exist File exists is True - F -- file File exists and is true for normal files - D -- Directory File exists and is directory-True -s--size The file exists and the size is not zero for true -r--read File exists and can be read as true -w--write File exists and can be written as true

= Detects whether two strings are equal and returns true for equality. [$a = $b] returns FALSE. != Detects whether two strings are equal and returns true if they are not equal. [$a! = $b] Returns TRUE. -Z Detects whether the string length is 0 and returns true for 0. [-Z $a] returns false. -N Detects whether the

First, the title description (60 points):Enter a string of lowercase letters (A~Z) through the keyboard. Write a string filter to filter out characters that are not the first occurrence if multiple identical characters appear in the string.For example, the string "ABACACDE" filter result is "ABCDE".Required implementation function: void Stringfilter (const char *

There are many shell operators, relational operators, arithmetic operators, Boolean operators, string operators, and file test operators1, arithmetic operatorsAcoustic Bash does not support simple arithmetic operations, and you can use the Expr toolTwo points Note: There are spaces between the expression and the operator, such as the 2 + 2, which is different from most of the programming languages

Title: String compressionEnter a string of lowercase letters (A~Z) through the keyboard. Write a string compression program that compresses the repeating letters of successive attendance in a string and outputs the compressed string.Compression Rules:1. Compress only consecutive occurrences of characters. For example,

Enter a string of lowercase letters (~ Z. Compile a character string filter program. If multiple identical characters appear in the string, filter out non-first-time characters. For example, the "abacacde" character string is "ABCDE ". Required implementation function: void stringfilter (const char * pinputstr, long li

A DNA sequence consists of an array of a/c/g/t four letters. The ratio of G to C (defined as Gc-ratio) is the total number of occurrences of the G and C two letters in the sequence divided by the total letter count (that is, the sequence length). In genetic engineering, this proportion is very important. Because high Gc-ratio may be the starting point of the gene.Given a long DNA sequence, and the required length
