Top Forums UNIX for Beginners Questions & Answers Help using combining variables with sed command (RHEL 7) Post 303043301 by RudiC on Thursday 23rd of January 2020 03:28:23 PM

Looks like the well known / infamous DOS line terminator problem:


Code:
$ RPT=test
$ sed 'p' $RPT
sed: can't read test: No such file or directory
$ RPT=test$'\r'
$ sed 'p' $RPT
 : No such file or directory

The first half of the error message is overwritten when the <carriage return> at the file name's end is performed.


So - get rid of that non-*nix feature. Use a *nix text editor, or the dos2unix command, or search these fora for many, many more options

NAME
dos2unix - convert text file from DOS format to ISO format SYNOPSIS
dos2unix [-ascii] [-iso] [-7] [-437 | -850 | -860 | -863 | -865] originalfile convertedfile DESCRIPTION
The dos2unix utility converts characters in the DOS extended character set to the corresponding ISO standard characters. This command can be invoked from either DOS or SunOS. However, the filenames must conform to the conventions of the environment in which the command is invoked. If the original file and the converted file are the same, dos2unix will rewrite the original file after converting it. OPTIONS
The following options are supported: -ascii Removes extra carriage returns and converts end of file characters in DOS format text files to conform to SunOS requirements. -iso This is the default. It converts characters in the DOS extended character set to the corresponding ISO standard characters. -7 Converts 8 bit DOS graphics characters to 7 bit space characters so that SunOS can read the file. On non-i386 systems, dos2unix will attempt to obtain the keyboard type to determine which code page to use. Otherwise, the default is US. The user may override the code page with one of the following options: -437 Use US code page -850 Use multilingual code page -860 Use Portuguese code page -863 Use French Canadian code page -865 Use Danish code page OPERANDS
The following operands are required: originalfile The original file in DOS format that is being converted to ISO format. convertedfile The new file in ISO format that has been converted from the original DOS file format. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWesu | +-----------------------------+-----------------------------+ SEE ALSO
unix2dos(1), ls(1), attributes(5) DIAGNOSTICS
File filename not found, or no read permission The input file you specified does not exist, or you do not have read permission. Check with the SunOS command, ls -l (see ls(1)). Bad output filename filename, or no write permission The output file you specified is either invalid, or you do not have write permission for that file or the directory that contains it. Check also that the drive or diskette is not write-protected. Error while writing to temporary file An error occurred while converting your file, possibly because there is not enough space on the current drive. Check the amount of space on the current drive using the DIR command. Also be certain that the default diskette or drive is write-enabled (not write-pro- tected). Notice that when this error occurs, the original file remains intact. Translated temporary file name = filename. Could not rename temporary file to filename. The program could not perform the final step in converting your file. Your converted file is stored under the name indicated on the second line of this message. SunOS 5.11 14 Sep 2000 dos2unix(1)
