Top Forums Shell Programming and Scripting To substitute multiple variable by their content in a file Post 302981600 by Don Cragun on Thursday 15th of September 2016 01:30:31 PM

I think something got lost in translation...

The for loop was needed in the BEGIN section of the script because the variable var contained multiple lines of replacements. The for loop copied six elements from the array T[] split out from the three lines in the variable RP into 3 elements in the array REPL[].

If you are saying that your replacement patterns are stored in a file instead of being stored in a variable, and you want to convert RudiC's suggested code:
Code:
awk -v RP="$var" '
BEGIN   {for (n=split(RP, T, "[\n:]"); n>0; n-=2) REPL[T[n-1]] = T[n]
        }
        {for (r in REPL) sub (r, REPL[r])
        }
1
' file

to work with that file (named DAE_20160915.txt in the following suggestion) as input instead of having the replacements specified by the shell variable var, you could do that with something like:
Code:
awk -F':' ' # Set input field separator to colon.
FNR == NR { # Gather replacement data from the 1st input file...
            REPL[$1] = $2
            next
          }
          { # Loop through the replacement array and make the desired
            # substitutions in subsequent input files...
            for(r in REPL) sub(r, REPL[r])
          }
1           # Copy (possibly modified) subsequent input file data to
            # standard output.
' DAE_20160915.txt file

GIT-NAME-REV(1) 						    Git Manual							   GIT-NAME-REV(1)

NAME
git-name-rev - Find symbolic names for given revs SYNOPSIS
git name-rev [--tags] [--refs=<pattern>] ( --all | --stdin | <commit-ish>... ) DESCRIPTION
Finds symbolic names suitable for human digestion for revisions given in any format parsable by git rev-parse. OPTIONS
--tags Do not use branch names, but only tags to name the commits --refs=<pattern> Only use refs whose names match a given shell pattern. The pattern can be one of branch name, tag name or fully qualified ref name. If given multiple times, use refs whose names match any of the given shell patterns. Use --no-refs to clear any previous ref patterns given. --exclude=<pattern> Do not use any ref whose name matches a given shell pattern. The pattern can be one of branch name, tag name or fully qualified ref name. If given multiple times, a ref will be excluded when it matches any of the given patterns. When used together with --refs, a ref will be used as a match only when it matches at least one --refs pattern and does not match any --exclude patterns. Use --no-exclude to clear the list of exclude patterns. --all List all commits reachable from all refs --stdin Transform stdin by substituting all the 40-character SHA-1 hexes (say $hex) with "$hex ($rev_name)". When used with --name-only, substitute with "$rev_name", omitting $hex altogether. Intended for the scripter's use. --name-only Instead of printing both the SHA-1 and the name, print only the name. If given with --tags the usual tag prefix of "tags/" is also omitted from the name, matching the output of git-describe more closely. --no-undefined Die with error code != 0 when a reference is undefined, instead of printing undefined. --always Show uniquely abbreviated commit object as fallback. EXAMPLE
Given a commit, find out where it is relative to the local refs. Say somebody wrote you about that fantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a. Of course, you look into the commit, but that only tells you what happened, but not the context. Enter git name-rev: % git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a 33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99~940 Now you are wiser, because you know that it happened 940 revisions before v0.99. Another nice thing you can do is: % git log | git name-rev --stdin GIT
