[GRASS-dev] batch search and replace from command line?

GRASS GIS GRASS GIS developer
1

I’m betting there is a Unix command to do a batch search and replace of one string with another in all text files in a directory.

But I don’t know what it is.

I’m trying to follow Glynn’s advice to create a library of common TclTk procedures that can be called without calling another instance of gm.tcl (i.e., without launching another GIS Manager window).

These procedures (e.g., Gm::errmsg) get called a LOT in many modules. I’d like a way of replacing every occurance of “Gm::errmsg” with “GmLib::errmsg” in all modules in the TclTk GUI directory.

Can someone tell me if this is possible and, if so, how to do it?

Thanks
Michael

With a fresh checkout from SVN (done about 3 hours ago),
I now get:

Error in startup script: can't create procedure "GmLib::errmsg": unknown
namespace
    while executing
"proc GmLib::errmsg { error args } {
    # send error report and optional message (args) to tk_messageBox

    set message ""

    if { $args !..."
    (file "/usr/local/grass-6.3.svn/etc/gm/gm.tcl" line 543)

when trying to launch gis.m

Best,

Works fine again.
Cheers for the quick fixing.

Looks like you got some response already, but on the GUI side on OSX, BBEdit's find and replace can search whole folders of files. Their free TextWrangler also can. Full GREP support in both, and you can filter files.

All generalizations are dangerous, even this one.

GNU sed has the following extension:

       -i[SUFFIX], --in-place[=SUFFIX]

              edit files in place (makes backup if extension supplied)

If you use that option, you can pass multiple filenames, and sed will
process each one separately, e.g.:

  sed -i -e 's/old/new/g' *.txt

Without the -i script, the source files will be concatenated and
processed as a single stream.

If you don't have GNU sed, you need a loop, e.g.:

  for file in *.txt ; do
      sed 's/.../.../g' "$file" > "$file".tmp && mv -f "$file".tmp "$file"
  done
