I get a md5 hash of a file with this command:
"cut" because I just want the hash. But there is a problem -> that doen't work with a path with spaces:
The result is "2.png)=" ... because of the space in the file name and the space is my delimiter.
Hi all!
Here is my problem :
$ more file
yougli:passwd:123456:3265:Yepa Yepo:/home/yougli:/bin/ksh
As you can see, in the field "information", there are two spaces between "Yepa" and "yepo".
My problem is :
$ PARAM='more file | cut -d":" -f5'
$ echo $PARAM
Yepa Yepo
Now i only... (2 Replies)

I'm new to shell programming, and am having a problem in a (Korn) shell program, which boils down to this:
The program reads a record from an input file and then uses a series of
"cut" commands to break the record into parts and assign the parts to
variables. There are no delimiters in the... (2 Replies)

md5(3) OpenSSL md5(3)NAME
MD2, MD4, MD5, MD2_Init, MD2_Update, MD2_Final, MD4_Init, MD4_Update, MD4_Final, MD5_Init, MD5_Update, MD5_Final - MD2, MD4, and MD5 hash
functions
SYNOPSIS
#include <openssl/md2.h>
unsigned char *MD2(const unsigned char *d, unsigned long n,
unsigned char *md);
void MD2_Init(MD2_CTX *c);
void MD2_Update(MD2_CTX *c, const unsigned char *data,
unsigned long len);
void MD2_Final(unsigned char *md, MD2_CTX *c);
#include <openssl/md4.h>
unsigned char *MD4(const unsigned char *d, unsigned long n,
unsigned char *md);
void MD4_Init(MD4_CTX *c);
void MD4_Update(MD4_CTX *c, const void *data,
unsigned long len);
void MD4_Final(unsigned char *md, MD4_CTX *c);
#include <openssl/md5.h>
unsigned char *MD5(const unsigned char *d, unsigned long n,
unsigned char *md);
void MD5_Init(MD5_CTX *c);
void MD5_Update(MD5_CTX *c, const void *data,
unsigned long len);
void MD5_Final(unsigned char *md, MD5_CTX *c);
DESCRIPTION
MD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output.
MD2(), MD4(), and MD5() compute the MD2, MD4, and MD5 message digest of the n bytes at d and place it in md (which must have space for
MD2_DIGEST_LENGTH == MD4_DIGEST_LENGTH == MD5_DIGEST_LENGTH == 16 bytes of output). If md is NULL, the digest is placed in a static array.
The following functions may be used if the message is not completely stored in memory:
MD2_Init() initializes a MD2_CTX structure.
MD2_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data).
MD2_Final() places the message digest in md, which must have space for MD2_DIGEST_LENGTH == 16 bytes of output, and erases the MD2_CTX.
MD4_Init(), MD4_Update(), MD4_Final(), MD5_Init(), MD5_Update(), and MD5_Final() are analogous using an MD4_CTX and MD5_CTX structure.
Applications should use the higher level functions EVP_DigestInit(3) etc. instead of calling the hash functions directly.
NOTE
MD2, MD4, and MD5 are recommended only for compatibility with existing applications. In new applications, SHA-1 or RIPEMD-160 should be
preferred.
RETURN VALUES
MD2(), MD4(), and MD5() return pointers to the hash value.
MD2_Init(), MD2_Update(), MD2_Final(), MD4_Init(), MD4_Update(), MD4_Final(), MD5_Init(), MD5_Update(), and MD5_Final() do not return val-
ues.
